  1. Question 1

    Q1. The cell wall of plants provides immense tensile strength due to the arrangement of cellulose. Which linkage is responsible for its straight-chain structure?

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

    Answer: Beta-1,4-glycosidic linkages

    Explanation: Cellulose consists of beta-1,4-glycosidic bonds, which allow for straight, unbranched chains. Alpha-1,4 bonds result in the helical structure of starch.
