Peroxisomes function in:

Answer: Breaking down hydrogen peroxide (catalase enzyme).

  • A Generating ATP through oxidative phosphorylation across an inner membrane
  • B Assembling amino acids into polypeptides at membrane-bound ribosomes
  • C Breaking down hydrogen peroxide (catalase enzyme)
  • D Packaging and modifying lipids for export via the Golgi apparatus

Correct answer: C. Breaking down hydrogen peroxide (catalase enzyme)

Explanation: Peroxisomes contain catalase enzyme that converts toxic H2O<sub>2</sub> to water and oxygen.
