  1. Question 1

    Q1. Before sucrose can be used in the glycolytic pathway of a plant cell, it must undergo which chemical process?

    • A) Reduction of Benedict's solution by glucose
    • B) Oxidation of the aldehyde group in fructose
    • C) Hydrolysis into glucose and fructose subunits
    • D) Condensation of two fructose monomers

    Answer: Hydrolysis into glucose and fructose subunits

    Explanation: Sucrose is a non-reducing sugar because its glycosidic bond involves the anomeric carbons of both glucose and fructose units.
