Investigation on the Effect of Temperature on Catalase

Aim:

In this investigation we are going to measure the effect of temperature change in a reaction between catalase and Hydrogen Peroxide.

Introduction

Catalase is an enzyme that's found in living things, it changes hydrogen peroxide into water and oxygen. In our investigation liver will be the source of catalase, we will measure the amount of time it takes for the catalase to complete its reaction with Hydrogen Peroxide and the effect of temperature on the rate of reaction. We will know when it's finished because there will be little oxygen produced and the fizzing will have stopped and there will not be much oxygen given out. The reaction is between catalase and hydrogen peroxide(H2O2).

Preliminary Work

Investigating the effect of temperature on the action of Enzymes. Using Pepsin and Egg white.This experiment was done to give us an idea for the prediction in our main experiment, we tested using an enzyme to give us a general idea of the effect of temperature on an enzyme, so that we could plan the range of temperature that we
