This is how it works: Hydrogen Peroxide Water + Oxygen H2O2 H2O + O I have trapped the yeast cells in jelly, so that when oxygen gas is formed, they rise to the surface. I will investigate the effect of different temperatures on the enzyme catalase. To do this I will heat the enzyme to different temperatures and see how long it will take the yeast cells to rise to the surface. SAFETY AND FAIRNESS To make sure this will be a safe and fair test I will wear safety goggles and not consume anything in the vicinity of the experiment. To make sure the results are fair I will use the same size yeast balls, use the same thermometer and same equipment.
