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.

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.?
