  1. Question 1

    Q1. During non-cyclic photophosphorylation, which specific complex is the only site capable of the photolysis of water molecules?

    • A) Photosystem I
    • B) Ferredoxin
    • C) Photosystem II
    • D) Plastoquinone

    Answer: Photosystem II

    Explanation: Only PSII (P680) is associated with the water-splitting complex. PSI is tempting because it also functions in light reactions but lacks photolysis.
