  1. Question 1

    Q1. In the initial phase of glycolysis, the cell must actually consume ATP. What is the purpose of this 'investment' phase?

    • A) To produce NADH
    • B) To phosphorylate glucose
    • C) To release CO2
    • D) To reduce pyruvate

    Answer: To phosphorylate glucose

    Explanation: ATP is used to phosphorylate glucose, making it more reactive. NADH is produced later in the energy-yielding payoff phase.
