  1. Question 1

    Q1. During the synthesis of a triacylglycerol molecule, three fatty acid chains attach to a glycerol backbone. What specific byproduct is released at each attachment site?

    • A) Hydrogen peroxide
    • B) Water molecule
    • C) Carbon dioxide
    • D) Hydroxyl group

    Answer: Water molecule
