  1. Question 1

    Q1. During light reactions, a plant cell switches from non-cyclic to cyclic electron flow to:

    • A) Produce additional ATP without NADPH
    • B) Generate oxygen for the atmosphere
    • C) Reduce NADP+ to NADPH
    • D) Split water molecules

    Answer: Produce additional ATP without NADPH

    Explanation: Cyclic flow produces only ATP to meet high demand. Non-cyclic is tempting because it produces both ATP and NADPH simultaneously.
