Art and Architecture in Daily Life Essay
When searching for an architecture piece that would catch the eye, there were worldly concerny to pick from. Finding iodin that would be remembered that was a little harder, but never the less the one that was found was so beautiful and very inspiring. There argon many buildings that are built for different reasons such as shelter, work, play, religious worship, or just for a personal relaxation. An architect by the name of Frank Lloyd Wright was a man who was very famous for his work, especially the creation called Fallingwater.Frank Lloyd Wright designed Fallingwater in 1935 which was known for its dynamism and for its integration. The construction would begin a year later and would not be completed until 1939. When finished Fallingwater would be one of Wrights finest creations, this would be due to Smithsonian Magazine counting Fallingwater as one of the 28 places to see beforehand you die (Colman, 2012). The website, http//www. openculture. com/2012/01/fallingwater-one-of-fran k-lloyd-wrights-finest-creations-animated. html shows a mini video of how the building was created and built.After reading about this creation and watching the video, visiting this location will be on my list of places to visit and explore with my children so they will be able to see the beauty of what you can do with nature. Fallingwater was an Organic Architecture phratry that Wright created for a family who owned a department store in Pittsburgh by the name of Edgar F. Kaufmann. They wanted to have a corner sway in a reclusive setting, which would epitomize man living in harmony with nature. And what better place than sitting in the middle of the wilderness surround by 5000 acres of nature.The home was built with local sandstone, reinforced concrete, steel and glass and hangs out over a beautiful waterfall on Bear Run that is surrounded by rocks, trees and rhododendrons (Powell, 2012). Wright had a strong passion for Japanese architecture and this had reflected in the design o f the Fallingwater. The interior also remained true to his vision which included cantilevered desks, earth-toned built-in sofas, polished stone floors, and large casement windows that allowed the outdoors to just shine in. The stone fireplace in the home was a boulder on the hill that was

Twainââ¬â¢s problematic ending of Huck Finn
The adventures of huckabackleberry Finn is known as atomic number 53 clean that has brought controversy from the time it was published in the year 1884 (Pearl par 1). It was banned in major(ip) public libraries many referring to it as trash. Currently, many regard it as a classical the Statesn novel though others still critic it in one area or the other. It is a novel from where either modern literature was derived and modern scholars and critics now treats it as great work of art in America (Pearl par. 1). Perhaps the greatest irony is that though it received great criticism, of all the MTs novels, it is the one that sold most immediately when it was published.Hunk Finn, as it is comm sole(prenominal) referred to, is label in the Mississippi river town of St. Petersburg, Missouri and the various locations along that river through Arkansas (SparkNotes, screen 21). The major conflict in the novel is portrayed as the main character (protagonist), huckaback struggles with a socie ty (antagonist) that is trying to civilize him. The conflict is also intensified as Hunk deals with Jim who is a black slave since Hunk must decide whether to reject Jim and please the society or protect him and follow his conscience. This essay shows that Twains final stage of the novel betrays the true subject of the work.The novel ends with the three boys Huck, gobbler and Jim escaping from a shed where they had been surrounded by about fifteen farmers guarding Jim, the black slave (Twain 361). They elucidate a hole in the wall to escape but as they does, Tom makes some noise and what follows is the shooting that leaves a bullet in Toms offshoot who portrays himself a hero. However, Huck and Jim are concerned about the condition of the leg and upon Jims suggestion they go to look for a doctor. This only worsens things for Jim who is captured by the locals and is chained as they bring Tom foot on a mattress accompanied by the doctor.By this time Huck has already depict home having left the two boys alone. The locals have decided to hang Jim though no one does it as they are afraid of compensating the slave owner. They are wherefore left with no other option than to treat Jim roughly until the time when the doctor comes and saves him by explaining that it is him who in fact saved Toms leg from deteriorating by nursing him (Twain 377). When Tom however learns that Jim was still in chains, he reveals to them that in fact Jim had already been specialize light thus was no yearlong a slave.This allows the reader to glimpse the character trait of Tom. Though he had known all along that Miss Wanton who had died two months earlier had set Jim free in her will, he did not say it because he felt that they needed to device a good plan to rescue Jim. If he had verbalize it earlier, Jim could not have gone through the sufferings that he had experienced. Huck arrived and on enquiring from Tom what he would do if Jim was freed he replied that he planned to re abi de Jim for all his troubles and sending him off as a hero.And he said, what he had planned in his head from the start, if we got Jim out all safe, was for us to run him down the river on the raft, and have adventures plumb to the mouth of the river, and then tell him about his being free, and take him back up home on a steamboat, in style, and pay him for his lost time, and write word ahead and get out all the niggers around, and have them waltz him into town with a torchlight procession and a brass-band, and then he would be a hero, and so would we (Twain 387).The Phelpses and Aunt Polly release Jim and feed him on hearing that he helped the doctor to nurse Tom. He is also given twoscore dollars as a payment for all his troubles (Twain 387). Tom and Huck are not through with their adventure and plan to go for another one to the Indian territories. Huck thinks that Pap had taken all the money but it is Jim who informs him that in fact the dead man he had seen in a floating star si gn was Pap (a cruel and drunk father).It is clear that though the writer of the novel was initially heading to the right direction in his writing, he looses focus (it may have been intentionally) as he comes to end of the novel in the way he presents the relationship between Huck and Jim. All along, the two boys had been together going through hardships and challenges during their adventure. They are seen doing different things together for example have to hide the inheritance of the Silk sisters in a coffin away from the greedy King and Duke. Huck even comes to a time when he had to decide whether to give the remaining Gherkin (food) from his provisions to Jim or take it himself (Paine Par. 20). Therefore every reader expects Hucks emotional attachment with Jim to grow. However when Tom appears, a different picture is portrayed with Huck remaining quiet when, they endanger Jims life by not telling Phelpses that Jim had already been released by the former Slave master and instead decides to device a plan as part of their adventure.When Jim goes to get the doctor, Huck leaves and runs to his uncles place leaving his friend. So then I crept into a lumber-pile to get some sleep and next time I waked up the solarize was away up over my head I shot out and went for the doctors house, but they told me hed gone away in the night some time or other, and warnt back yet. Well, thinks I, that looks powerful bad for Tom, and Ill dig out for the island right off. So away I shoved, and turned the corner, and nearly rammed my head into Uncle Silass stomach (Twain 367).The other business arises because though the novels subject is directed to the theme of freedom, at the end Jim who is supposed to be free is not still free. This stub be attributed to the mistake that Tom made though intentionally. Jim, who has been technically free for all that time they were in the adventure, is still bound in chains, first in the home of Phelpses before the escape and then by the local s who captured him when he went to bring the doctor who would treat Tom. It is ridiculous that Miss Wanton can not set Jim free when she is alive and has to wait till she dies and does it in her will. Old Miss Watson died two months ago, and she was ashamed she ever was going to sell him down the river, and said so and she set him free in her will. (Twain 383) In conclusion, it is clear that the work of Mark Twain was based on the theme of racism, slavery and freedom thus different readers can critic it using different views. The plot flows smoothly from the beginning but the problem arises in the ending as the reader is left wondering wherefore there is no development in Hucks character -who is the protagonist and who is supposed to develop in all areas as the plot develops.

Herbal Products for personal casre Essay
Aromatherapy is complementary and alternative medicine (CAM) technique in which various indispensable oils (including essences and extracts) derived from plants, flowers, fruits, leaves, herbs, stems, shrubs or trees be utilize to promote healing of the proboscis, mind and the spirit, and to encourage wellness and well-being of the individual. Aromatic oils suck up been utilized in healthcare since ancient times by the Egyptian civilization and the Arabs. Modern aromatherapy was given special interest in France.The French found that oils had several anti-septic properties and thence could be utilized to cut out infections. Some of the physicians in France administer inhering oils. Certain guidelines mentioned in the aromatogram assistant the physician to decide which essential oil has to be utilized. The patients sample of tissues or bole fluids is cultured in the laboratory. Different essential oils are added to the growing cultures. The specific essential oil that inhibit s issue of the microorganisms is identified and utilized.Essential oils are substances similar to hormones (or chemical messengers) present in the body, that play an important manipulation between cells. It contains about 200 to 3000 different compounds. Studies suggest that they can play a role against cancer, and have other effects such(prenominal)(prenominal) as stimulation (lime), calming (lavender), analgesic (clove), anti-spasmodic and cough suppressant (lavender). On the skin, it seems to have an antiseptic (tea tree), astringent (lemon grass), protectants (sandal wood), stimulant (rose) and cooling (Chamomile) effect.Aromatherapy can be administered in several forms such as skin or external applications (including cosmetic use and applications over the hair), inhalation, and internal consumption. External applications of essential oils involve applying the agents on the skin through and through baths, massages, friction, compresses, cosmetic use (in the form of creams, m l ook ats, compresses, lotions, ointments, etc), hair applications, etc. such(prenominal) applications help in relaxation, stimulating the skin and make the individual feel more energetic and lively.several(prenominal) toxic substances and metabolic wastes present on the skin are inactivated and destroyed. It also helps to reduce body aches and reduce swellings. Rarely (5% of the cases), the individual may develop inflammatory disorders of the skin (such as dermatitis), and experience symptoms such as irritation, rashes, pruritis, etc. In such circumstances, the treatment should be discontinued. Internal consumption of essential oils may be required to treat several disorders involving the internal organs (such as the digestive tract).However, some of these oils may footing the liver. Hence, they have to be administered strictly by a physician, and the patients condition should be monitored. The essential oil can also be administered utilizing a diffuser or nebulizer (through inhalat ion). The oils can be utilized to treat several breathing or lung disorders, and to improve mood. The molecules of the essential oils can enter the body through the nose, gain access through the lungs, from where it can diffuse into the bloodstream.It can remain in the blood for 30 minutes to several days. Sprays are also available which provide effect for a short period. Aromatherapy has emerged as a separate branch of science and profession because of the huge benefits. Lavender may increase star wave functions related with relaxation and stress-release (Balac, 1992). Chronic smokers felt a reduced urge to consume baccy with aromatherapy (Rose & Behm, 1994). The quality of life in individuals with cancer and anxiety improved afterward being administered Chamomile (Wilkinson, 1995).Stevenson (1994) show that heart patients requiring surgery felt better when their feet were being massaged with neroli oil. Post-operative patients had reduced nausea and needed fewer painkillers aft er inhaling peppermint oil (Tate, 1997). In fact aromatherapy can be utilized to treat several conditions such as infections (such as Herpes Zoster Virus, Herpes Simplex Infections, etc), arthritis, skin disorders, musculoskeletal disorders, sleeplessness, anxiety, distress, anticancer therapy problems, anorexia, body aches, etc.Any individual can learn about aromatherapy by reading books, attending seminars or going to school that train in aromatherapy. The National Association of Holistic Aroma-therapists (NAHA) is setting up standards for gift licenses and administering training. The individual who wants to become an aroma-therapist should have a good knowledge and practice of chemistry, botany, human physiology, etc. The aroma-therapist is creditworthy for administering treatment sessions on the patients such as massages.During the patients first session, he/she will ask the questions to get a detailed outlook of the past and present medical history. According to the patients c omplaint and the diagnosis of the condition, he/she will prepare essential oils using different individual components. The massages are similar to the Swedish and the Sports methods. The aroma-therapist also gives complete details of the procedure to the patient, advices about any precautionary measures to be taken and educates the patient about the benefits and risks of the procedure.

Is it ethical to mask your true emotions in order to get along with others? Essay
fair playfulness is the best policy. Or is it not? As children, we were taught that neary is regulateing the equity straightforward. We were told that it is world sincere, genuine, trustworthy, loyal, and fair. We were taught to tell the truth at all times, despite consequences. Our parents taught us to do our own homework, keep a friends secret, return stuff we found, and keep our promises. But as we grew older, the linage between the truth and falsehood started to blur. We began to tell and accept half-truths.We began to resort to telling white lies to get out of potentially disastrous situations. We are confronted normal by basic issues of honesty. If a opus is forbidden by his wife to smoke, should he confess that he took a few sticks from his buddys pack when they were at the bar earlier that night? Is it real imperative that he do so when he only smoked two, whitethornbe three, cigarettes? Does he live to be completely honest with his wife or can he get away with som ething that unnoticeable?If you are anti-Bush and attending a formal dinner where every single person at your tabularise is pro-Bush, should you be completely honest and let everyone know your sentiment, at the risk of alienating yourself? Or should you relieve your Bush-bashing for another time and another place? Should you just go along with the conversation and act oblivious towards the topic? As Saki (1929) said, A little inaccuracy sometimes saves tons of explanation. But is this ethical? Or must honesty always reign supreme? Some people, institutions, and dogmas bolster the virtue of being completely, straightforwardly honest.But is it not also square that sometimes people who are brutally honest find more satisfaction from being brutal than from being honest? The philosopher Immanuel Kant claimed that the telling of a truth is the perfect duty. He said that it cannot be superseded by other values not scour the concern for the life of a friend or the loyalty to someone we love. He insisted that the act of assembly is always incorrect morally. However, many scholars have found Kants philosophy to be too uttermost(prenominal) and self-serving. In the book On Moral Grounds, moral philosophers Daniel Maguire and A.Nicholas Fargnoli (1991) state, Very simply, Kant would not be the man you would wish to stand between you and someone intent on murdering you at least if Kant knew where you were. Furthermore, Maguire and Fargnoli (1991) refer to Kants stand on lying to explore the restrictions of universal moral principles. They write, Universalization is an unrealistic and inaccurate abstraction that passes over the fact that thither are exceptions to valid moral principles. Also, To protect other values, like the life of an intend victim or a legitimate secret, exceptions to truth-telling must be made. In her book Lying, philosopher Sissela Bok (1978) says, The also-ran to look at an entire practice rather than at their own isolated case much b linds liars to cumulative malign and expanding deceptive activities. Those who begin with white lies can come to resort to more ghost and more serious ones The aggregate harm from a large number of marginally harmful instances may, therefore, be highly undesirable in the end for liars, those deceived, and honesty and trust more generally. For the author, there is danger in all acts of lying because there is a possibility that the telling of even the smallest of lies may affect coarse discourse. She emphasizes that lies have a tendency to spread. Lies, even the most seemingly insignificant ones, can gravel and affect other aspects of our lives. Nowadays, most people are utilitarians when it comes to the topic of honesty. White lies are okay because they probably dont hurt anyone only we avoid outright lies that have the possibility of offending or harming others. However, the utilitarian attitude to truthfulness has to have its limitations.As author Austin OMalley said, Those who think it is tolerable to tell white lies soon grow color-blind. Telling a white lie -like reassure a sick person that he looks much better when, in fact, he doesnt- is alright but if it becomes a habit, there could be dire consequences. A person may lose credibility and attentiveness from his partner, family or friends. Masking ones true emotions to keep the peace in a sealed situation or in commit to get along with others can be ethical, but there are limits to how far you can go with faking how you really feel.There is a very fine line between truth and fiction, between lies and white lies. Even the Bible makes this distinction. The commandment does not say, Thou shalt not lie instead, it says, Thou shalt not bear false witness. This means that lies that do not cause harm for example, telling the hostess that a meal she made is really peachy when it was, in fact, absolutely horrible- is acceptable. In this instance, the lie is told to make the person feel better about he rself and to show appreciation for her efforts.Here, the lie was rattling made in attempt to do something salutary. However, a lie that could have grave consequences such as when a person who has caused damages to his neighbors property does not admit that he did so to avoid having to pay for the cost of repairs- is a sin. To mask ones true feelings in order to get along with others is fine as long as a person keeps to the boundaries and the motivation shadower the lie or the masking of the truth is valid. Another consideration would be the frequency with which the person disguises his true opinions or feelings.If done too often, the person could risk losing his sense of self and authenticity. In The Critic as Artist, Oscar Wilde (1905) says that a little bit of sincerity is a dangerous thing, and a great ingest of it is absolutely fatal. For people in relationships, he may have a point. Honesty may not be the best policy when we are hiding aspects of ourselves from the other pe rson, when we do not want to be revealed, to be known completely. Honesty may not be the best policy when we do not want to get into trouble or when we are avoiding conflict.Honesty may not be the best policy when we are trying to spare the others feelings, when we do not want the other to feel hurt or disappointed. In a relationship, people may tell lies because they cerebrate that it is the kind thing to do. Robert Brault once said that, Today I bent the truth to be kind, and I have no regret, for am I am far surer of what is kind than I am of what is true. dread lies, which are intended for anothers benefit, are usually made under these kinds of circumstances.But turn the motivation behind this type of lie may seem valid, there are still those who deal that the concept is flawed. Critics of utilitarianism say that people often poorly estimate the consequences of their actions or specifically undervalue or ignore the harmful consequences to society (e. g. , mistrust) that th eir lies cause (Mazur, 1993). Also, the concept of lying for the sake of a greater good may cause a further blurring of the line between moral justifications supporting the greater good and empty excuses.

African American in 19th Century Essay
The Civil war after effects set the scene for what would live a long road of discovery, hardship, violence, and freedom however, during this process of transition the American people went through stirred up as well economical changes which added additional stress to an already stressed nation where servicemany groups became dreadful and were subjected to racism which crossed over the boundary of freedom and Justice for all.Equality had become an endangered liberty guaranteed by a country build upon democracy, regrettably the African American people were not the exclusively ones to suffer many vast groups faced hard days in America at the knock over of the century several violent attacks were specifically carried out on the African American workforce and women flat though, the civil war brought a lot of changes it produced little or no results for African American men however, it did bring harsher persecution all over the country, whereas mass numbers of black men were lynche d in the lower grey states in a show of defiance.The Emancipation Act did nothing for the tweed man provided understood provided less for the African black man who were still unable to vote in addition to having phone line jobs with adequate pay many were forced back to the farm as sharecroppers in spite of the set backs they percervered through the racial remarks and slanders.

How Will Science and Technology Change Our Lives Essay
The Contribution of India to the earth of Science & Technology dates back to ancient times. India had the best of the scientists in different fields of experience and engineering erudition mathematics, medicine, architecture, astronomy, geometry, chemistry, metallurgy, etc. Aryabhatta was a fifth century mathematician, astronomer, astrologer and physicist. He introduced the concept and symbol for Zero and the decimal place value system to the world of mathematics. Bhaskaracharya introduced Chakrawat Method or the Cyclic Method to solve algebraic equations. Kanad, a sixth century scientist developed the atomic theory which says that the material universe is made up of anu/atom, which cannot be further subdivided and they are indivisible and indestructible. This is what the modern atomic theory says. In the field of medicine, India was a front runner.Susruta was a pioneer in the field of surgery. Charak, considered the father of ancient Indian science of medicine, was the numbe r 1 to talk about digestion, metabolism and immunity as important for health and so medical science. The science of Yoga was developed in ancient India as an allied science of Ayurveda for healing without medicine. India was a pioneer in many technologies such as metallurgy (steel making, iron, zinc, bronze etc) and Architecture. The findings in Moganjatharo civilisation stand testimony to this fact. The structures such as Iron Pillar in Delhi, Taj Mahal, Gol Gumbaz, Mahabalipuram, Tanjore Periya Kovil are some examples of Indias supremacy in the Architecture. Science and modern font IndiaIndian scientists have played a stellar role in the development of India. In the bypass span of its post-independence history India has achieved several great scientific achievements. Indian scientists have proved their mettle in the face of international sanctions and have made India one of the scientific powerhouses of the world. Sir M. Visvesvaraya, Sir CV Raman, Jagadish Chandra Bose, Subraman iam Chandrasekar, Srinivasa Ramanujam, Homi Bhaba, Vikram Sarabhai are some of the name calling leading the pack of Indian scientists. How technology impacts masss life?Technology affects peoples lives by improving medicines, provides better treatment for diseases and insures a longer life. It improves transportation by helping people move from one corner of the world to other in hours by using transportation run such as Airways, Railways, or even Bus Transportation. Modern Technology dislodged peoples life style and the way they live. For example, now its possible to surf Internet on TV, watch programs, pause peppy TV, and even playback live shows. Internet surfing is a technology revolution.Because of that technology, a person could know what is accident on the other side of the world. Due to Internet, it is now possible to say that the world is at your fingertips. late discoveries and scientific breakthroughs such as Cracking the DNA code and Mapping the Genome may complet ely change the way people look even before they are born. Diseases that are passed through generations, like diabetes, degenerative diseases may be eliminated from the unborn child. What India should do?While India is uniquely positioned to use technology for progress, it has in the new-fashioned past lagged behind in the quality and spread of science look into. The need for a strong science eco-system based on a sound research foundation is the need of the hour for India to become a Global Power house. The key to continued success for India in a globalised knowledge-driven economy is building a higher education system that is superior in quality and committed encouragement of relevant research in science and technology. To achieve this, the government, universities, companies, venture capitalists, and other stakeholders should come together to enable Research and nurture to achieve superiority in the field of science and technology.

The Effects of Substrate Concentration, Reaction Time and Enzyme Concentration on Enzyme Reactions
The do of Substrate Concentration, Reaction cartridge clip and Enzyme Concentration on Enzyme Reactions Corey von Ellm-St. Croix Rachael Kwan ID 20427841 Matthew Hrycyshyn & Saeideh Mayanloo Biol 130L, Section 017 Wednesday, 930am-1220pm, 151 November 09, 2011 A living organisation wangles its activity through enzymes. Enzymes are made from hundreds or even thousands of amino acids connected in a very unique and particularised order. Almost all enzymes are proteins, except for ribozymes. The chain of amino acids therefore folds into a unique shape.That shape non only allows the enzyme to carry out specific chemical reactions precisely to act as a very efficient catalyst. The enzyme speeds that reaction up tremendously. separately enzyme reacts with one specific reactant called a substrate that will form its products. The purpose of the experiments is to fall the effects of substrate assimilation, reaction cartridge clip and enzyme assiduousness on the direction of an e nzyme reaction. Amylase is a digestive enzyme prime in both the saliva and the littler in streakine.Salivary amylase is a hydrolytic reaction that breaks down stiffen molecules by systematically breaking off the maltose molecules from the ends of starch chains. The maltose is further broken down by another enzyme. Phosphorylase is an enzyme that systematically removes glucose molecules by consumes phosphorous acid to break the beta-1-4-glucosidic bonds in starch. The interaction of phosphate with the glucosidic bond resolutions in the formation of glucose-1-phosphate and the loss of a chain unit in starch. In the reverse reaction the glucose part of glucose-1-phosphate is added as a recent chain unit and phosphate is set free.This reversible enzymatic polymerization occurs with little change in free energy and therefor the reaction may choose to go both way. ace runnel is a interrogation for the presence of starch in which the sample turns blue- color in color when a few er disembark downs of potassium iodide dissolvent are placed on the sample. A disconfirming unity trial run is when the reaction dust white-livered-bellied in work. It is the reaction between one and the coiled polymer of glucose known as amylase in starch that causes the colour change. The reaction occurs when straight amylase chains form helices in which the iodin corporation pass inside.Glycogen also receives a colour change because it is a glucose polymer as well exclusively its structure differentiates from starch which therefore forms a browned colour change. The iodine showify does not bestow for mono or disaccharides because they are too small to capture the iodine. The benedicks show is employ to detect the presence of minify sugars. Reducing sugars are sugars with a free aldehyde or ketone group. The free responsive carbonyl group allows all monosaccharides to be trim back sugars. The same goes for disaccharides as some also suffer the free reactive carbonyl group.The colour of precipitate formed when the Benedicts visitation acquires a compulsory result depends on the concentration of reduce sugars present. A green colour change indicates that few reducing sugars are present. Orange indicates a higher concentration, red an even higher concentration and brown is the highest concentration colour change. A prejudicial test for reducing sugar occurs when the Benedicts solution remains its blue colour.

Figure1 above represent the time it took each salivary amylase concentration to reach endpoint (when test for starch became negative. Discussion Salivary Amylase The Iodine tests control is the presence of starch. If starch is presence accordingly the control is positive resulting in a blue-black colour change. The first iodine test or if you refer to table 1, gave a positive result for only test tube 5 which contained 1% starch suspension. Clearly starch is present based on just the component of the solution.A negative contr ol in an iodine test will result in maintenance of the yellow colour of iodine. match to table one the test tubes containing 10% salivary amylase solution, 5% salivary amylase solution, 2% salivary amylase solution and 1% salivary amylase solution resulted in a negative control result. This is due to the fact that all that is present is the enzyme salivary amylase and water and therefore no starch. The Benedicts test control is the presence of reducing sugars (sugars with a free aldehyde or ketone group). If a reducing sugar is present past a positive control reaction will occur. A positive control reaction is when a colour of the blue Benedicts solution turns green, orange, red or brown after boiling.Each colour represents the concentration of reducing sugars present, green being the lowest and brown the highest. Referring back to table 2, test tubes 1 and 2 resulted in a positive control reaction. Even though test tubes 1 and 2 contained only salivary amylase the tap water used to dilute the amylase solution may contain some starch which would in turn become maltose a reducing sugar. The 10% salivary amylase (test tube 1) resulted in an orange colour change due to the fact that a higher enzyme concentration would more likely produce enough reducing sugars to result in an orange colour change. The 5 % salivary amylase (test tube 2) resulted in a green colour change which describes a low concentration of reducing sugars.This makes sense as a lower enzyme concentration would result in less reducing sugar being made through the enzymatic reaction between starch and amylase. A negative control reaction for the Benedicts test occurs when the Benedicts blue solution remains the same. Referring back to table 2 test tubes 3, 4 and 5 resulted in a negative control reaction. This may be due to the fact that the enzyme concentration were too low to produce enough reducing sugars from the starch found in the tap water to warrant a colour change. The starch (substrate) would for a substrate-enzyme interlinking with salivary amylase to produce maltose and salivary amylase. In conclusion enzyme concentration does play a factor in the speed of an enzymatic reaction.The results of Table 3, the second iodine test performed, is used to determine when the starch added with the different concentrations of salivary amylase has reached its endpoint and has been fully hydrolysed into maltose. The endpoint has been reached once the iodine test gives a negative control result which occurs once no starch or very few is present. According to the experimental data presented in table 3 enzyme concentrations again played a role in the speed of the reaction. 10% salivary amylase took 90 seconds where as 1% salivary amylase took 780 seconds. The starch (substrate) would for a substrate-enzyme complex with salivary amylase to produce maltose and salivary amylase.Test tube 10 + 15 will result in a positive control reaction all the time because it is comprised of wate r and starch. With no salivary amylase enzymes starch will always be present which is the positive control in an iodine test. A trend was found that as the salivary concentrations were halved the time to reach endpoint was doubled, leading me to call back an backward proportionality to be present between enzyme concentration and time to reach end point. Table 4 was another Benedicts test performed after the each combination of test tube had reached its endpoint. The positive result in a Benedicts test occurs once a green, orange, red or brown colour change occurs because of the presence of reducing sugars.Test tubes 16-19, containing the different concentrations of salivary amylase, resulted in a positive control reaction because the starch (substrate) would for a substrate-enzyme complex with salivary amylase to produce maltose and salivary amylase and due to the fact that maltose is a reducing sugar which happens to be the control for a Benedicts test, a positive control reactio n will occur. The negative control reaction for a Benedicts test is when the Benedicts solution remains blue signifying the absence of reducing sugars. According to table 4, test tube 20 only contained water and the starch suspension with no amylase present a substrate-enzyme complex will not form which will not result in a reducing sugar. Phosphorylase Table 6 is another iodine test.The positive control reaction for an iodine test is when the solution turns blue-black. The experimental data given in table 6 shows that test tubes 6 and 7 gave a positive reaction for starch because of the 1. 5 ml of 0. 2% starch found in solution. The negative control reaction is when the solution remains the colour of iodine, yellow. Test tube 1 through 5 gave negative result because they either do not contain any starch in solution or the amount of starch present is too little (starch earth) and must be in presence of phosphorylase to synthesis a larger starch chain that can be reacted with the io dine test to provide a positive result. Table 8 is once again another iodine test.With the addition of phosphorylase some of the test tubes that gave a negative result in the previous iodine test (table 6) may now give a positive result because of the ability of the reaction between phosphorous acid and glucose to from glucose-1-phosphate and one less glucose unit in starch chain to go in either direction. Therefore a test tube with a starch primer may use the phosphorylase to synthesis into a starch chain. The same is for the solution that gave a positive reaction may turn negative in the presence of phosphorylase to form a starch primer and glucose-1-phosphate. Referring to table 8 the test tubes that resulted in a positive control reaction were 2,3,6 and 7.Because test tubes 6 and 7 were already gave positive results in previous iodine test (table 6) and did the same in this iodine test can only regard as that a synthesis of a larger starch chain had occurred or the starch chai n had not removed enough glucose bonds to result in a negative iodine control result. In test tube 7 the phosphorylase was boiled which would denature the enzyme so that it could not perform its task and therefore phosphorolysis could not take place and therefore test tube 7 would have to remain a positive control result. Test tubes 2 and 3 were primarily negative in previous iodine test but resulted in a positive control result when the enzyme phosphorylase was added.Table shows that over time both solutions grew more intense in colour signifying the synthesis of a longer starch chain. Test tube 2 had the starch primer and glucose-1-phosphate to start with and therefore took less time to give a positive control result. Test tube 3 did not contain the starch primer and I believe should not have given a positive control result. Test tube 3 did however contain the glucose-1-phosphate and perhaps may have started its own starch chain. This may have been done by having a glucose-1-phos phate and the glucose form a substrate-enzyme complex to give phosphoric acid and a larger glucose chain. The negative results were test tubes 1, 4 and 5 each contained the starch primer.Test tube 1 contained glucose but phosphorylase does not react with single glucose molecule and therefore test tube 1 will always give a negative control result. Test tube 4 used boiled phosphorylase and therefore the modify enzyme would not be able to perform function which would result in an always negative control result. Test tube 5 had the right condition but perhaps never moved in one direction of the enzymatic reaction for too long resulting in a starch primer being present the whole time though it may have had potential to yield a positive control reaction. This shows that temperature do affect an enzyme. A buffer was also used in the reaction to allow for the proper pH levels to be obtained and therefore pH levels also affect enzymes.Overall end-to-end the experiment it was determined tha t substrate concentrations, reaction time and enzyme concentration effect the direction of an enzyme reaction.
