Jimmy Hamilton VM Biology Coursework Investigation. Investigation of Reaction Rates Between Hydrogen Peroxide and Catalase. Aim: To investigate the effect of enzyme concentration on the rate of reaction. Information: An enzyme is a biological catalyst found in all living organisms and controls all the chemical reactions that occur. A catalyst is a substance that speeds up a reaction, so enzymes speed up reactions in living organism. Enzymes are found in all living cells and here they are called intracellular enzymes. Enzymes are also found in the digestive system, where they are called extracellular enzymes. Thousands of reactions occur simultaneously in a living organism, each of which is controlled by an enzyme. All enzymes share common properties: 1) The act on a particular substance called the substrate, and will only act on this one substance, i.e. the are specific. For example; maltase (enzyme) acts on maltose(substrate) to make glucose (product.) 2) They can work in...
