  1. Question 1

    Q1. During a high-intensity workout, a muscle cell hydrolyzes ATP to ADP. How much energy is released per mole of ATP under standard conditions?

    • A) 3.7 kcal/mol
    • B) 7.3 kcal/mol
    • C) 14.6 kcal/mol
    • D) 10.5 kcal/mol

    Answer: 7.3 kcal/mol

    Explanation: The terminal phosphate bond of ATP releases 7.3 kcal/mol; ADP is the product, but it contains fewer high-energy bonds than the original ATP.
