Science Coursework. Skill P - Planning my Investigation (8 marks) Aim For my coursework I will be performing an investigation into an experiment using hydrogen peroxide (2H2O2) as a substrate and Catalase as the enzyme, which will be produced by a potato. The enzyme Catalase is present in all aerobic tissues and catalyses the breakdown of hydrogen peroxide into water and oxygen. Hydrogen peroxide is a toxic by-product of many bio-chemical reactions within organisms, including aerobic respiration. The equation for this is: Catalase Hydrogen peroxide oxygen + water + Catalase (2H2O2) (2O2) (2H2O) This reaction can be discussed in terms of the activation energy and its effect on the rate of a chemical reaction. In order to get this reaction started, either some energy or a catalyst is required. Without it, the reaction would be much slower. In the case of my experiment, the Catalase will bind temporarily to the hydrogen peroxide particles they catalyse. In doing...
