Final answer:
Catalase catalyzes the decomposition of hydrogen peroxide into water and oxygen, with the reaction being 2H2O2 → 2H2O + O2.option D
Step-by-step explanation:
The enzyme catalase is known for its role in breaking down hydrogen peroxide into water and oxygen. This reaction occurs in the peroxisome of the cell and is crucial for protecting the cell from oxidative damage caused by hydrogen peroxide.
The reaction that is normally catalyzed by catalase in the peroxisome is D. 2H2O2 → 2H2O + O2. Hydrogen peroxide is a byproduct of various metabolic processes and can be harmful to cells if not regulated. Catalase efficiently converts this potential toxin into less harmful substances, water, and oxygen.
