Cellular organelles that interact with hydrogen peroxide are called?
Correct answer: D. Peroxisomes
- A. Glyoxysomes
- B. Lysosomes
- C. Ribosomes
- D. Peroxisomes
Explanation
The correct answer is Peroxisomes. Peroxisomes are organelles that contain enzymes, such as catalase, specifically involved in the metabolism of hydrogen peroxide. They help in detoxifying cells by converting hydrogen peroxide into water and oxygen. This function is crucial for maintaining cellular health and preventing damage from reactive oxygen species.Glyoxysomes, while a type of peroxisome found in plants, are primarily involved in lipid metabolism, not directly in hydrogen peroxide breakdown.Lysosomes are involved in digesting cellular waste and do not interact with hydrogen peroxide.Ribosomes are involved in protein synthesis and have no role in hydrogen peroxide metabolism.
