  1. Question 1

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

    • A) Succinate Dehydrogenase reaction (Complex II)
    • B) Isocitrate Dehydrogenase reaction (Citric Acid Cycle)
    • C) Phosphocreatine Kinase reaction
    • D) Pyruvate Dehydrogenase reaction

    Answer: Phosphocreatine Kinase reaction

    Explanation: Phosphocreatine Kinase reaction is responsible for rapid ATP production through phosphagen system, whereas the other options are part of cellular respiration that takes longer to produce ATP.
