  1. Question 1

    Q1. A plant cell is experiencing a temporary shortage of NADP+, causing it to switch from non-cyclic to cyclic photophosphorylation. Which product is still generated?

    • A) Production of NADPH
    • B) Photolysis of water
    • C) Release of oxygen
    • D) Synthesis of ATP

    Answer: Synthesis of ATP

    Explanation: Cyclic photophosphorylation only produces ATP via Photosystem I, whereas non-cyclic photophosphorylation produces both ATP and NADPH using both photosystems.
