  1. Question 1

    Q1. When a chloroplast is deficient in NADP+ and shifts to cyclic photophosphorylation, what is the primary energetic product generated by the process?

    • A) NADPH and Oxygen
    • B) ATP only
    • C) ATP and NADPH
    • D) Glucose and ATP

    Answer: ATP only

    Explanation: Cyclic flow only produces ATP to meet high energy demands; NADPH is only produced during non-cyclic photophosphorylation via Photosystem I.
