Peroxisomes A) use an enzyme to destroy H₂O₂ that is toxic to the cell. B) are a type of lysosome. C) are responsible for the atrophy of unused muscles. D) are sites for synthesis of fatty acids, steroids, and phospholipids. E) All of the answers accurately describe peroxisomes.

Question

Quizplus · Accepted Answer

Peroxisomes contain enzymes, including catalase, that break down hydrogen peroxide (H₂O₂) into water and oxygen. Hydrogen peroxide is toxic to cells, so peroxisomes play an important role in protecting the cell from its harmful effects. Answer: D Peroxisomes are sites for the synthesis of fatty acids, steroids, and phospholipids. They also contain enzymes involved in the catabolism of certain amino acids and other molecules. Therefore, E is incorrect because it states that all answers accurately describe peroxisomes, but B and C are incorrect statements. The correct answers are A and D.
