  1. Question 1

    Q1. Bioenergetics focuses on the flow of energy in living systems. How many high-energy phosphate bonds are typically found in a single molecule of ATP?

    • A) One phosphoanhydride bond
    • B) Three phosphoanhydride bonds
    • C) Four phosphoanhydride bonds
    • D) Two phosphoanhydride bonds

    Answer: Two phosphoanhydride bonds

    Explanation: ATP contains two high-energy phosphoanhydride bonds. Option B is incorrect because the bond between ribose and the first phosphate is a low-energy ester bond.
