  1. Question 1

    Q1. During a metabolic reaction in a liver cell, one mole of ATP is hydrolyzed to ADP and inorganic phosphate. What is the standard amount of energy released?

    • A) 3.4 kcal/mol
    • B) 8.5 kcal/mol
    • C) 7.3 kcal/mol
    • D) 14.6 kcal/mol

    Answer: 7.3 kcal/mol

    Explanation: Hydrolysis of one terminal phosphate bond releases 7.3 kcal/mol; 14.6 kcal refers to the total energy of both high-energy bonds combined.
