Hydrogen peroxide is a substance that is produced as a byproduct of many cell processes. however, hydrogen peroxide is toxic to cells. in fact, if cells are unable to break down hydrogen peroxide, they become poisoned and die. catalase is an enzyme that is found in all living tissues. this enzyme speeds up the reaction that breaks down hydrogen peroxide into less harmful substances. what substances are formed as a result of this reaction?

Water and Oxygen

Explanation:

Hydrogen peroxide is a harmful substance that can damage the membrane system of the cell. Cells have catalase enzyme in peroxisomes. The enzyme catalase catalyzes the breakdown of hydrogen peroxide into water and oxygen. In this way, the potential causative agent of oxidative stress, that is hydrogen peroxide, is rendered harmless by enzyme catalase.

weathering is the answer.

answer: b: experiments that showed that all cells are similar in how they metabolize and in their composition

explanation:
