Grace Doran 10/28/15 Grade 9 Liver Catalase Lab Purpose: The experiment was conducted in order to test whether or not the liver catalase performed different when denatured. Also to test what happens when we change the pH of the reaction. Introduction/ Background Information: A liver is vital in getting rid of toxic substances in the body. It uses enzymes which are proteins that help to complete chemical reactions. The enzyme used in the liver is a catalase enzyme. This enzyme helps to break down hydrogen peroxide (H2O2) into water and oxygen. However enzymes may under extreme heat or pH levels may become denatured and nonfunctional.

AP Lab #13 Enzyme Activity August 28, 2014 Sarah Shafik PURPOSE: Background: Enzymes are proteins that speed up the rate of a chemical formula. They lower a reaction?s activation energy, and are not consumed by the reaction either. Hypothesis: If the enzyme concentration decreases, then the enzyme activity will also decrease. If the substrate concentration decreases, then the enzyme activity will also decrease. If the pH increases, then the enzyme activity will also increase. If the temperature increases, then the enzyme activity will also increase. Key Terms Definitions: Enzymes: a macromolecule serving as a catalyst Catalase: a common?enzyme?found in nearly all living organisms

Name ____________________________ Per._____ Enzyme Rate of Reaction Introduction: Enzymes are molecular substances found in cells.? Enzymes act as catalysts and most are proteins.? Enzymes bind temporarily to one or more of the reactants of the reaction they catalyze. In doing so, they lower the amount of activation energy needed and thus speed up the reaction.?

AP Biology Lab #2 Enzyme Catalysis Overview: In this lab you will observe the conversion of hydrogen peroxide (H2O2) to water and oxygen gas by the enzyme catalase, and then measure the amount of oxygen generated. You will also calculate the rate of an enzyme-catalyzed reaction. Objectives: Before doing this lab, please review the following from your text and/or notes: Structure, function of enzymes How temperature, pH, enzyme concentration and substrate concentration affect the initial reaction rates of enzyme-catalyzed reactions Review the terms: Catalyst Catalase Catalysis After doing the lab, you should be able to:
