MODEL RELEASED. Catalase reaction experiment. Catalase is an enzyme that decomposes hydrogen peroxide (H2.O2) into water and oxygen. Hydrogen peroxide is formed in cells from oxidation reactions. Measured volumes of catalase are added to the conical flask (lower centre) to react with a substance containing hydrogen peroxide. Oxygen that is produced is piped through the beaker and collects in an inverted burette (down left), displacing water so that its volume can be measured.
