Do all living tissues contain catalase? Claim, evidence, and reasoning
allsm [11]

Yes, the all living tissues contains the catalase, Catalase protects cellular organelles and tissues from damage by peroxide.

<h3>Do all living tissues contain catalase?</h3>

Catalase is a common antioxidant enzyme which is present in all living tissues of an organism and it is responsible for the degradation or reduction of hydrogen peroxide to water and molecular oxygen using either iron or manganese as a cofactor.

Liver, potatoes and other living tissues contain the enzyme catalase. This enzyme breaks down hydrogen peroxide which is a harmful by-product of the process of cellular respiration. If it builds up in concentration in the cells, the cells are adversely affected which leads to serious complications in the organisms.

So we can conclude that all living tissues contains the catalase, Catalase protects cellular organelles and tissues from damage by peroxide.
