  1. Question 1

    Q1. A 16-year-old athlete is training for a marathon. Which process is responsible for the energy production in this situation?

    • A) Anaerobic glycolysis producing 2 ATP per glucose molecule
    • B) Aerobic respiration producing 36-38 ATP per glucose molecule
    • C) Lactic acid fermentation producing 2 ATP per glucose molecule and releasing lactic acid
    • D) The citric acid cycle producing 2 ATP per glucose molecule

    Answer: Aerobic respiration producing 36-38 ATP per glucose molecule

    Explanation: Aerobic respiration is responsible for energy production in aerobic conditions, unlike anaerobic glycolysis or lactic acid fermentation.
