    Question

    The organelle that protects the cell from oxygen toxicity is:

    A.

    Lysosome

    B.

    Peroxisome

    C.

    Quantasome

    D.

    Oxysome

    Correct option is B


    The correct answer is: (b) Peroxisome
    Explanation: Peroxisomes are small membrane-bound organelles present in eukaryotic cells that contain oxidative enzymes such as catalase and oxidase. These enzymes help break down hydrogen peroxide (H₂O₂) — a toxic byproduct of metabolism — into water and oxygen, thus protecting the cell from oxygen toxicity.
    Reaction:
    mathematica
    Copy code
    2H₂O₂ → 2H₂O + O₂
    Information Booster: • Peroxisomes are also involved in fatty acid β-oxidation and detoxification of alcohol in liver cells. • Defective peroxisomes can cause Zellweger syndrome, a lethal genetic disorder.
