  1. Question 1

    Q1. Glycogen is highly branched to allow rapid glucose mobilization. Which mechanism is responsible for the branch points in its structure?

    • A) Linear elongation via alpha 1-4 linkages
    • B) Inversion of glucose units via beta 1-4 linkages
    • C) Branch point formation via alpha 1-6 linkages
    • D) Dehydration between carbon 1 and carbon 2

    Answer: Branch point formation via alpha 1-6 linkages

    Explanation: Branching in amylopectin occurs via alpha 1-6 glycosidic bonds, which distinguishes it from the linear alpha 1-4 amylose.
