    What is aerobic respiration?
    Question

    What is aerobic respiration?

    A.

    Respiration through skin

    B.

    Respiration without molecular oxygen

    C.

    Respiration through gills

    D.

    Respiration in presence of oxygen

    Correct option is D


    The correct answer is (d) Respiration in presence of oxygen.
    Key Points:
    · Aerobic respiration is the process by which cells generate energy in the presence of oxygen.
    · During aerobic respiration, glucose is completely broken down into carbon dioxide and water, releasing a significant amount of energy in the form of ATP (adenosine triphosphate).
    · This process occurs in the mitochondria of the cell and is the most efficient way of producing energy.
    Information Booster:
    · Respiration through skin: Known as cutaneous respiration, seen in some amphibians and certain other organisms.
    · Respiration without molecular oxygen: This is anaerobic respiration, where energy is generated without the use of oxygen, often producing lactic acid or ethanol as by-products.
    · Respiration through gills: Known as branchial respiration, this is typical in aquatic animals like fish.
