Effect of Temperature on Enzyme Activity Yeast cells contain catalase, an enzyme which helps convert hydrogen peroxide to water Figure 4: Catalase catalyzes the decomposition of hydrogen peroxide to water and oxygen. and oxygen. This enzyme is very significant as hydrogen peroxide can be toxic to cells if allowed to accumulate. The effect of catalase
