In the human cell, _ is responsible for oxidizing hydrogen peroxide.
Correct answer: C. Peroxisomes
- A. Lysosomes
- B. Mitochondria
- C. Peroxisomes
- D. Glyoxysomes
Explanation
Option A: Lysosomes are another type of cell organelle that contains enzymes that can break down waste products and foreign invaders. However, lysosomes do not produce hydrogen peroxide.Option B: Mitochondria are the powerhouses of the cell, responsible for producing ATP, the cell's energy currency. They do not produce hydrogen peroxide.Option C: Peroxisomes are small, membrane-bound organelles that are found in most eukaryotic cells. They contain enzymes that carry out oxidation reactions, which can produce hydrogen peroxide as a byproduct. Hydrogen peroxide is a reactive molecule that can damage cells. Peroxisomes are small organelles that contain enzymes involved in various metabolic processes, including the breakdown of fatty acids and the detoxification of harmful substances. One of the enzymes present in peroxisomes is called catalase, which facilitates the breakdown of hydrogen peroxide into water and oxygen. This prevents the accumulation of hydrogen peroxide, which can be damaging to cells if it builds up in high concentrations. Option D: Glyoxysomes are a type of peroxisome that is found in plant cells. They are involved in the breakdown of fatty acids to produce carbohydrates. They do not produce hydrogen peroxide. describes organelles that contain hydrolytic enzymes that break down endocytosed foreign particles or even intracellular fragments.

About Cell Structure and Function
Animal, plant, prokaryotic and eukaryotic cells are compared through their membranes, cell walls, nuclei and cytoplasmic organelles. The work includes the structures and functions of mitochondria, chloroplasts, ribosomes, endoplasmic reticulum, Golgi apparatus and lysosomes, as well as chromosome organization and the distinction between chromatin and chromosomes.
