Q: Q: Peroxisomes carry out oxidation reactions that break down what acids? Read this paragraph and choose the correct option from the provided answers: Peroxisomes Peroxisomes are small, round organelles enclosed by single membranes. They carry out oxidation reactions that break down fatty acids and amino acids. They also detoxify many poisons that may enter the body. Alcohol is detoxified by peroxisomes in liver cells.
