What is the function of a peroxisome?

• A. Maintain acidity of the cell
• B. Contain toxic reactions
• C. Protein synthesis
• D. Protein glycosylation

Answer: (B)

Verified step by step guidance

1. Understand that peroxisomes are small, membrane-bound organelles found in the cytoplasm of eukaryotic cells.
2. Recognize that the primary function of peroxisomes is to contain and neutralize toxic reactions, particularly those involving hydrogen peroxide (H2O2), a byproduct of various metabolic processes.
3. Learn that peroxisomes contain enzymes such as catalase and oxidase, which help in breaking down hydrogen peroxide into water and oxygen, thus preventing potential damage to the cell.
4. Note that peroxisomes are also involved in lipid metabolism, including the breakdown of very long-chain fatty acids through beta-oxidation.
5. Understand that while peroxisomes play a role in detoxification and lipid metabolism, they are not directly involved in maintaining cell acidity, protein synthesis, or protein glycosylation.
