  1. Question 1

    Q1. Glycogen is a highly branched polymer of glucose. Which specific bond is responsible for creating the branches in its molecular structure?

    • A) Beta-1,4-glycosidic linkages at branch points
    • B) Alpha-1,6-glycosidic linkages at branch points
    • C) Alpha-1,2-glycosidic linkages at branch points
    • D) Phosphodiester linkages at branch points

    Answer: Alpha-1,6-glycosidic linkages at branch points

    Explanation: Alpha-1,4 bonds form the straight chain, while alpha-1,6 bonds create the branches. Beta bonds are found in cellulose.
