Aim To investigate whether the enzyme Catalase is affected by different temperatures by using catalase from potato at a range of different temperatures and to measure how enzyme has worked by measuring the amount of oxygen collected Introduction * Living cells continuously carry out chemical reactions and as a by-product produce hydrogen peroxide. It is a toxic substance which can destroy the cells if not immediately broken down. * This breakdown is carried out by the enzyme catalase, which is produced in all living cells. * Catalase breaks down the hydrogen peroxide into water and oxygen making it harmless to the cells. Hydrogen CATALASE Peroxide Water + oxygen 2H2O2 2H2O+ O2 Therefore enzyme catalase is the catalyst. Hydrogen Peroxide is the substrate. Catalase is the fastest enzyme known. When it comes into contact of Hydrogen peroxide, frothing shows rapid production of oxygen. . Catalase is to break down. This is what enzymes do. Catalase is the...
