MISEP Chemistry 512 – Jacobs Enzyme Catalyst Lab - Formal Report – August 8‚ 2007 ABSTRACT This investigation examined what would happen to the rate of an enzyme-catalyzed reaction if the concentration of substrate changed. We hypothesized that if the concentration increased‚ then the reaction rate would also increase. To test our question‚ we varied a combination of substrate and buffer‚ totaling 6mL‚ with a constant amount of 2 drops of catalyst. The enzyme catalyst‚ peroxidase‚ increased

Action of enzymes as catalysts in biochemical processes * Enzymes acts as catalyst and increase the rate of all the chemical reactions. * Enzymes are also described by two properties like all other catalysts. It composed of two main functions. * The first function is that‚ they increase the rate of chemical reactions by without consumed themselves or undergo any change or alteration in the reaction. . ( Zemitec et‚al 2008). * The second function is‚ they increase reaction rates

The Effect Of Enzyme Concentration On Enzyme Activity The pancreatic duct in individuals who have cystic fibrosis frequently becomes blocked‚ reducing or preventing the release of pancreatic enzymes into the small intestine. The aim of this activity is to investigate the effect of a reduction in enzyme concentration on the rate of reaction‚ in this case the breakdown of protein by protease enzymes. Aim – Milk powder contains a white protein called casein. A white suspension of

Enzyme Activity Lab Hypothesis: 1] Are enzymes reusable? Yes‚ enzymes are reusable. 2] Which of the following do you think contain catalase? [Manganese dioxide‚ chicken meat‚ apple‚ carrot‚ potato‚ or chicken liver] I think that the manganese dioxide‚ apple‚ and carrot contain the catalase. 3] Would grinding the materials affect enzyme activity? I think that grinding the materials will increase enzyme activity. 4] Would temperature affect enzyme activity? I think that

Discovery Creative He sat lazily on the cold ceramic tiles of his bedroom‚ resting his back against the rigid wooden framework of his single bed. With legs outstretched‚ chest gently dipping up and down and his forehead submissively being supported by his fingertips‚ Jonas Schmidt reminisced upon the caring and affectionate figure of his father. He reflected upon their journey; a collage of memories flashed through his mind- from the struggle in fleeing Germany and the rise of Nazi power‚ to the

Effect of the Changes in the Environment to the Functionality of the Enzymes Introduction a. Background In our everyday lives‚ enzymes are used in our bodies‚ and in nature around us‚ to speed up the chemical reactions happening constantly‚ which happens by lowering the amount of activation energy needed to start various reactions. The way this works is by attaching the particular substrate to the active site of the enzyme‚ where it will start to aid the chemical reaction. Then‚ the allosteric

Enzyme Report Case 1 - Hereditary Fructose Intolerance 1 & 2. Enzymes take on a variety of roles in the human body at the cellular level. Specifically‚ they aid in the breakdown of macronutrients such as glucose and fructose so that the body can use them. Although reactions within the body would occur without enzymes‚ enzymes provide control because the reaction is not needed all of the time. Enzymes function in specific environments such as temperature or pH; some enzymes are specific

Discovery of Antibiotics “Penicillin” As we know‚ the 19th and 20th centuries were among some of the most drastic years the United States experienced. While we often look at it as a time of bad and wrong decisions‚ there were many positive things that came from them. The most prominent of them were the number of discoveries and inventions that took place and were of great benefits then and now. One of those was the discovery of antibiotics in 1928‚ by Dr. Alexander Fleming. Before this discovery

“There are some scholars who would argue that “the Age of Discovery” should be called “the Age of Destruction.”. I agree and disagree with the statement because it was in fact the “Age of Discovery” because transculturation along with the spread of Christianity began and there was an increase of agriculture and economy. Nevertheless‚ it too‚ is appropriate to be called the “Age of Destruction” because the birth of diseases affected the entire population‚ enslavement with the African Americans caused
