temperature was above 40Ëšc the enzyme did not work as efficiently‚ even with the extra energy‚ as they had become deformed. Where the enzyme does not work so well or does not even work at all the active site if the enzyme had changed. The enzyme had not died as it is not a living organism. With the shape of the active site changed the enzyme is unable to perform the "lock and key" action the enzyme is meant to do in order to catalyse a reaction. The specified enzyme is shaped to "lock" on to

The Affects of pH on Peroxidase Enzyme Claire Bell Biology 1130 Jazmen Myers Section 36 Abstract Peroxidase is a turnip enzyme; it is used in the oxidation of hydrogen peroxide to lower activation energy‚ speeding up the reaction. The activity of peroxidase is highly dependent on its environment and most importantly the pH level. Peroxidase has been the focus of many recent studies and is believed to possibly reduce swelling among other things. We conducted an experiment testing

The Effect of Starch on the Activity of Amylase with pH Variable Lab Report‚ Fall 2011 East Tennessee State University Department of Biological Sciences By: Shelby Brackett Date Performed: October 10‚ 2011 Lab Instructor: Joseph Kusi Biology 1111‚ Section 018 Abstract Enzymes are very important in chemical reactions. They are used to speed up the reaction taking place. They act by binding to a specific substrate and form an enzyme-substrate complex that may put stress on chemical bonds

- - - - - - Effect of Substrate Concentration on Catalase Aim: An experiment to find out how the concentration of hydrogen peroxide affects the rate of reaction of the enzyme catalase. Background Information: Enzymes such as catalase are globular protein molecules with catalytic properties. A catalyst is a substrate which can alter the rate of reaction without itself undergoing any permanent change. As they are not changed my reactions which they catalyse‚ enzymes can be used

Running head: LAB 5: INVESTIGATING AN ENZYME-CATALYZED REACTION Lab 5: Investigating an Enzyme-Catalyzed Reaction September 24‚ 2014 Principles of Biology 120.601 Mrs. Annemarie Duncan Abstract: (Burmania) This experiment was performed in order to examine ways in which a potato catalase enzyme reacts to various assays with differing variables. To do so a baseline assay (undiluted extract and room temperature H2O2) was used within the experiment with only one other variable changed in

BIOLOGY IA A Factor That Will Affect Enzyme Activity The Question Effects on Enzyme activity: investigating the effects of mixing Hydrogen Peroxide with Catalase extracted from potatoes at different temperatures‚ and then comparing the results with the same method‚ except to replace the Potato juice with MnO2 Hypothesis Since enzymes are a type of protein‚ they will be destroyed at high temperatures and activity rates will go down at low temperatures. Also‚ if done at low temperature

Effects of Changes in Physical Properties on Enzyme Activity By Alex Hoffmann First Individual Lab Report Wednesday 7:30-10:15pm 10/24/12 Meghan Duell Abstract The goal of this lab was to determine the effects of certain physical properties on enzyme activity. Enzyme activity was measured by the height of the bubbles that appeared after the enzyme was added which are proportional to the rate of the reaction when time is constant. The fact that enzyme activity is affected by physical

Enzyme Activity Over Different Concentrations and Effects The goals of this experiment were to examine the effectively of enzymes on samples of different enzyme concentrations and substrate concentrations. In addition‚ the experiment tested how effective enzymes are on samples of pH levels and temperature levels. A. Effect of Enzyme Concentration Hypothesis: With half as much enzyme concentration then the reaction rate will be half as much than when the enzyme concentration is equal

The Effects on Enzymes By Bailey Rose The Effects on Enzymes Bailey Rose 10/31/2011 Abstract In this lab exercise‚ the study of enzyme catalase‚ we viewed the breakdown of hydrogen peroxide into water and oxygen. The purpose was to isolate catalase from starch and measure the rate of activity under different conditions. Changes in temperature and pH along with Substrate Concentration and Enzyme Concentration were the conditions tested in the experiment. Our class performed
