Investigating the effect of Temperature upon the Enzyme Catalase Introduction: Living cells continually carry out chemical reactions and produce hydrogen peroxide. It is a toxic substance which would destroy the cell if it's not immediately broken down. This breakdown is carried out by the enzyme CATALASE, which is produced in Living cells. Catalase breaks down the hydrogen peroxide into water and oxygen making it harmless to the cell. Hydrogen Catalase Peroxide Water + Oxygen 2H2O2 2H2O + O2 Therefore Catalase is the catalyst. Hydrogen peroxide is the substrate Catalase is the fastest enzyme known when it comes into contact with H2O2, Bubbles (frothing) show rapid production of oxygen. Aim: To study the action of Catalase upon potato at different temperatures. I plan to assess the reaction by measuring the volume of oxygen produced in three minutes. Method: 1. Grate 5g potato. This will increase the surface area and also break open the cells to release the enzyme Catalase. 2. Put...
