Biology GCSE Coursework: Planning In this experiment I am going to try and find out the factors that affect enzyme controlled reactions by using the Catalase in potato. Enzymes are non-living and act as biological catalysts, which speed up reactions. They can change shape if the temperature changes. Enzymes are made up of active sites (the lock) and only certain shaped substrates can fit into them to cause a chemical reaction. To work out this experiment, I am going to use a formula of: 2H2O2-using catalase to become 2H2O+O2 I will use a set of five pH's to get my readings from the collected oxygen. The amount of oxygen is directly related to the rate of catalase activity. Factors affecting the rate of an enzyme-controlled reaction are the independent; pH buffer and the controlled ones; temperature, substrate concentration, time (rate of reaction), and enzyme concentration. The factor I am going to investigate...
