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

Observation Zinc Shot: Silver color‚ some pieces are shiny while the majority is dull. Tear shaped pieces (round at base with pointed top). No odor. Zinc Granular: Silver in color‚ semi shiny‚ flaky appearance. No odor. Zinc Sheet: Sheet of metal‚ flat pieces that are about 3 inches wide & 2 inches in length & 0.02 inches in height. Each piece has a dull side and a shiny side. Silver in color‚ the dull side has a darker shade of gray. No odor. Zinc Powder: Gray very fine powder. No odor

Results Figure 1 shows that the response of the tissue increased with bath concentration of ACh (M). The logarithms of bath concentration for each response were used to form a clear sigmoidal formation‚ and thus depict a more clear relationship between concentration and response. Figure 1 shows the increasing rate of response as bath concentration increased‚ before plateauing around the highest concentrations. Responses ranged from 0.685-100%‚ while bath concentrations of ACh ranged from 2 x 10-10

Studying the Rate of Reaction of catechol oxidase and how it affects pH levels Introduction: In this lab‚ we studied the activity of an enzyme that is found in fruits and vegetables called catecholase or catechol oxidase. An enzyme is a protein molecule that is a catalyst. Catechol oxidase is the enzyme in fruits and vegetables that turns them that undesirable brownish color; also commonly referred to as bruising or bruised. When walking through your regular grocery store and you find yourself in

Abstract Enzyme catalysis was observed in order to analyze how changes in temperature‚ pH‚ enzyme concentration‚ and substrate concentration affected an enzyme-catalyzed reaction. This experiment analyzed the rate of enzyme-catalyzed reactions and observed the correlation between catalase activity and products formed. It was found out that the rate of an enzyme-catalyzed reaction starts off rapidly‚ decreases‚ and levels off or completely stops‚ and can be further affected by environmental factors

My lab group studied the effect of PH on reaction rate/ enzyme activity measured by foam height. PH is the measure of the concentration of hydrogen ions in a solution. The higher the hydrogen ion concentration‚ the lower the pH. Every enzyme has an optimal PH‚ meaning they have a very small window in which they are most active. Our enzyme (potato smoothie) had an optimal PH of 7.0-7.5. We know this because we measured the enzyme’s reaction rate by measuring foam height. The largest foam height we

Enzymes Reactions to Changes in Substrate and Inhibitors Benjamin J. Mora Coronado University of Texas Rio Grande Valley at Edinburgh Abstract Purpose for the experiments was to test the enzymes in various scenarios and see how changing this would affect the rate of reaction. The enzyme source used in the experiments was Turnip Extract. Concentrations of Turnip extract for activity 1 where o.5ml‚ 1.0ml‚ and 2.0 ml as for the rest of the activities 2 Through 4 stayed at a consistent concentration

The purpose of the first week experiment was to determine the effect of Nitrophenyl phosphate concentration‚ the substrate‚ on the enzyme‚ acid phosphatase‚ reaction. In an enzyme reaction‚ there is substrate that binds to the active site of the enzyme and product is the end result. The enzyme is the catalyst for the reaction which means that it speeds up the process. Without enzymes‚ the majority of reactions would not occur because the activation energy level would be unattainable. With this in
