GCSE Chemistry/Biology Joint Investigation The Decomposition of H2O2 Using Catalase in Yeast as a Catalyst Planning Aim In this experiment I will investigate the effect of using a catalyst (enzyme), called catalase found in yeast, on the decomposition of H2O2. To measure the rate of this reaction I will collect the O2 given off when the yeast and H2O2 react. I will then see how temperature effects the reaction. Safety 1. Goggles will be worn at all times to prevent any splashes from irritating the eye. 2. Any spills will be cleared up straight away. 3. H2O2 is flammable so the substance will be kept away from naked flames. 4. The gas syringe will be placed in a clamp to prevent it being knocked over. 5.
