oxygen

Explanation:

Catalase is an enzyme found in living tissuea of plants and animals. Its role in living tissues is to break down hydrogen peroxide produced during cellular metabolism. Hydrogen peroxide is ahighly toxic substance which should not be allowed to accumulate in the tissues. If it were to accumulate in the tissues, it would interfere with cellular metabolism. Enzyme catalase breaks down hydrogen peroxide into water and oxygen which are non-toxic substances. Liver contains enzyme catalase.
