What organelle contains oxidase enzymes that detoxify harmful chemicals?

• A. Peroxisomes
• B. Mitochondria
• C. Golgi apparatus
• D. Lysosomes

Answer: (A)

Peroxisomes are specialized organelles that play a crucial role in the detoxification of harmful substances. They contain oxidase enzymes, which catalyze a variety of reactions, including the conversion of hydrogen peroxide—a potentially harmful byproduct of lipid metabolism—into water and oxygen. This process is vital for maintaining cellular health, as hydrogen peroxide can be damaging to cells if allowed to accumulate.

In addition to detoxification, peroxisomes are involved in lipid metabolism and the breakdown of fatty acids through beta-oxidation, also contributing to the overall metabolic processes within the cell. Their unique enzymatic capabilities make peroxisomes essential for protecting cells from oxidative stress and maintaining metabolic balance.
