  1. Question 1

    Q1. In the Calvin cycle, several steps require energy. Which specific phase utilizes the reducing power of NADPH?

    • A) Carbon fixation
    • B) Reduction of 3-PGA
    • C) Regeneration of RuBP
    • D) Release of oxygen

    Answer: Reduction of 3-PGA

    Explanation: The reduction phase of the Calvin cycle uses NADPH to convert 3-PGA into G3P (PGAL), requiring both ATP and NADPH.
