Question

________ are membrane-bound organelles that contain enzymes like catalase, which catalyzes the breakdown of H2O2 to H2O and O2.

A) Lysosomes
B) Peroxisomes
C) Ribosomes
D) Mitochondria
E) Vaults

Answer 1

The organelles that contain enzymes like catalase for the detoxification of hydrogen peroxide are called peroxisomes.

Step-by-step explanation:

The membrane-bound organelles that contain enzymes like catalase, which catalyze the breakdown of H2O2 into water (H2O) and oxygen (O2), are called peroxisomes. Like lysosomes, they are involved in different functions including lipid metabolism and chemical detoxification.

The enzymes within peroxisomes transfer hydrogen atoms from various molecules to oxygen, producing hydrogen peroxide as an intermediate. Peroxisomes contain the enzyme catalase which then breaks down this potentially harmful hydrogen peroxide into less reactive and safe compounds, protecting the cell from oxidative damage.
