An investigation into how the volume of oxygen given off by catalase changes with the concentration of hydrogen peroxide Introduction This experiment investigates how the volume of oxygen given off by catalase is affected by a change in the concentration of hydrogen peroxide. The experiment will be carried out by adding a constant volume of yeast to different concentrations of hydrogen peroxide solution. Catalase is an enzyme that breaks down hydrogen peroxide into water and oxygen. The equation for this is as follows: 2 H2O2 2 H2O + O2 This reaction occurs in our bodies all the time because hydrogen peroxide is poisonous. Catalase is found in all living cells, both in animals and plants. The conversion is extremely efficient, as one catalase enzyme can turnover 40,000,000 molecules/second. Here is a picture of a catalase enzyme from E. coli. Prediction I predict that as the concentration of hydrogen peroxide doubles, the rate of oxygen production, the volume...
