Jamie Harris 3P Investigating the effects of temperature on an Enzyme Catalase. In this investigation I am going to find out how much cm³ of oxygen (O2) can be collected after a reaction has taken place between hydrogen peroxide (H2O2) and catalase in a set time, of three minutes. Catalase Hydrogen Peroxide Water + Oxygen 2H2O2 2H2O + O2 Background information * Catalase Catalase is a very fast reacting enzyme; it is found in many living cells, it breaks hydrogen peroxide down into water and oxygen. In fact one molecule of catalase can deal with six million molecules of hydrogen peroxide in 1 minute. Hydrogen peroxide is toxic so needs to be changed into harmless substances. * Enzymes An enzyme is a biological catalyst, it alters the rate of reaction without changing itself. Enzymes are proteins; they have a very precise shape, which forms a specific active site, (see diagram below) on the enzyme. Each enzyme can break...
