  1. Question 1

    Q1. A 16-year-old athlete feels muscle fatigue during a sprint due to the rapid ATP production in this situation. Which process is responsible for the rapid ATP production?

    • 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: Lactic acid fermentation producing 2 ATP per glucose molecule and releasing lactic acid

    Explanation: Lactic acid fermentation produces 2 ATP per glucose molecule and is responsible for rapid ATP production in anaerobic conditions, unlike anaerobic glycolysis or aerobic respiration.
