Sam Dixon 11E The Effect Of Substrate Concentration On The Activity Of The Enzyme Catalase Aims This is an experiment to examine how the concentration of the substrate hydrogen peroxide affects the rate of reaction of the enzyme catalase. Background Information Enzymes such as Catalase are protein molecules, which are found in living cells. They are used to speed up reactions in the cells. Catalase is an enzyme found in food such as potato and liver. It is used for removing Hydrogen Peroxide from the cells. Hydrogen Peroxide is the poisonous by-product of metabolism. Catalase speeds up the decomposition of Hydrogen Peroxide into water and oxygen as shown in the equations below. Formula: Catalase Hydrogen Peroxide---------------------->Water + Oxygen Catalase 2H2O2------------------->2H2O+O2 This type of reaction where a molecule is broken down into smaller pieces is called an anabolic reaction. Apparatus Needed For The Experiments 1. Gas Syringe 2. Metal Stand 3. Liver 4. Hydrogen Peroxide 5. Test Tubes 6....
