Which of the following is a primary function of peroxisomes in eukaryotic cells?

• A. Breakdown of fatty acids through beta-oxidation
• B. ATP production via oxidative phosphorylation
• C. Protein synthesis
• D. Photosynthesis

Answer: (A)

Verified step by step guidance

1. Understand the role of peroxisomes in eukaryotic cells. Peroxisomes are specialized organelles involved in various metabolic processes, including the breakdown of fatty acids and detoxification of harmful substances.
2. Recall the process of beta-oxidation. Beta-oxidation is a metabolic pathway where fatty acids are broken down into acetyl-CoA molecules, which can then enter the citric acid cycle for energy production. This process occurs in peroxisomes and mitochondria.
3. Eliminate incorrect options based on the known functions of peroxisomes. For example, ATP production via oxidative phosphorylation occurs in mitochondria, not peroxisomes. Protein synthesis occurs in ribosomes, and photosynthesis occurs in chloroplasts of plant cells.
4. Focus on the correct function of peroxisomes. Their primary role includes the breakdown of fatty acids through beta-oxidation, as well as detoxification of hydrogen peroxide using the enzyme catalase.
5. Conclude that the correct answer is 'Breakdown of fatty acids through beta-oxidation,' as this aligns with the primary function of peroxisomes in eukaryotic cells.
