Answer:
Peroxisomes
Explanation:
Peroxisomes are the membrane-bound organelles present in eukaryotic cells only. These are specifically abundant in liver cells and are involved in the breakdown of fatty acids. Peroxisomes have enzymes that catalyze metabolic reactions in which hydrogen from various compounds is transferred to oxygen. These reactions produce hydrogen peroxide. Catalase is the enzyme present in peroxisomes that rapidly splits excess hydrogen peroxide to water and oxygen, rendering it harmless.
