Answer:
The function of catalase is to protect cells from toxic effects by some reactive chemicals, such as hydrogen peroxide.
Explanation:
As a result of the metabolism, each organism causes some chemical substances to be produced, for example, hydrogen peroxide. Catalase catalyzes the reaction, decomposing hydrogen peroxide to compounds less dangerous for cells, for example, in water and oxygen. In the following reaction the function of catalase is shown:
2H2O2 -----------> 2H20 + O2
