Which of the following organelle is associated with production and destruction of H2O2 ?: (A) Peroxisomes, (B) Lysosomes, (C) Ribosomes, (D) Golgi bodies
Answer is A. Oxidases use O2 to oxidize organic substances and produce hydrogen peroxide (H2O2). Breakdown of hydrogen peroxide (H2O2), a potentially dangerous product of fatty-acid oxidation. It is catalyzed by the enzyme catalase. Both enzymes are present in peroxisomes. Though Lysosomes produce H2O2 it can't degrade it.
