Have a little read: ... Investigation to determine the effect of substrate concentration on the rate of breakdown of hydrogen peroxide by the enzyme catalase. Aim: To investigate the effect of substrate concentration on the breakdown of hydrogen - peroxide by the enzyme catalase. Introduction: Enzymes are protein molecules and they can be found in living cells. They are biological catalysts, and their function is to speed up reactions within each cell. Each enzyme will only catalyse one reaction, as they are very specific. Catalase is an enzyme. It is a protein molecule and it is found in food like potatoes, liver and celery. It can also be found in yeast. Catalase catalyses the reaction of hydrogen-peroxide into water and oxygen. Its function is to remove hydrogen peroxide from cells. The equation for this reaction is 2H2O2 --> 2H20 + O. This type of reaction is called an catabolic reaction. This reaction is important as it breaks down
