  1. Question 1

    Q1. A student calculates the energy budget of Glycolysis. Which comparison between 'total ATP produced' and 'net ATP gain' is accurate?

    • A) The net gain is 2 ATP while the total produced is 4 ATP
    • B) The net gain is 4 ATP while the total produced is 2 ATP
    • C) The net gain is 36 ATP while the total produced is 38 ATP
    • D) The net gain is 0 ATP because all are used in the Krebs cycle

    Answer: The net gain is 2 ATP while the total produced is 4 ATP

    Explanation: Glycolysis produces 4 total ATP but consumes 2, resulting in a net gain of 2 ATP per glucose.
