    Which one of the following statements about the events of non-cyclic photophosphorylation is not correct?

    A)  Photolysis of water takes place

    B)  Oxygen is released

    C)  Only one photosystem participates

    D)  ATP and NADPH are produced

    Correct Answer: C

    Solution :

    In non-cyclic phosphorylation, electrons derived from the photolysis of water are raised to higher energy levels in PS-I and PS-II and pass along an electron transport chain of carrier molecules to NADP reductase. This enzyme transfers electrons to \[NAD{{P}^{+}}\]to make NADPH, which provides reducing power for light dependent reactions of photosynthesis.
