MDCAT Biology MCQ #427

  1. Question 1

    Q1. ATP contains three phosphate groups, but which specific linkage is an anomaly by not being a high-energy 'tilde' bond?

    • A) Ribose and the first phosphate
    • B) First and second phosphate
    • C) Second and third phosphate
    • D) Adenine and ribose

    Answer: Ribose and the first phosphate

    Explanation: The bond between ribose and the first phosphate is a low-energy ester bond. The terminal phosphoanhydride bond is tempting but high-energy.
