PLAN Friday 19th April 2002 Catalase Coursework. Title: Factors affecting the rate of enzyme mediated reaction. Aim: To find out how the concentration affects the rate of reaction. Introduction: Enzymes are proteins that control vital biological processes. They often act as biological catalysts. In the human body enzymes control the breakdown of food and reactions which make chemicals such as fats, carbohydrates, proteins and DNA. Enzymes are used today in a wide range of industrial processes. These include fermentation, baking, cheese making, tenderising meat and treating leather. The table summarises some of the enzymes used in industrial processes. The enzyme catalase is present in blood to prevent the build-up of dangerous peroxides. If a small piece of liver is added to hydrogen peroxide, a rapid evolution of oxygen is seen. The catalase acts as a catalyst and speeds up the decomposition of hydrogen peroxide. 2H202(aq) ==> 2H20 + 02(g) Catalase is an extremely effective catalyst. One molecule...
