  1. Question 1

    Q1. When NADP+ levels are low in the stroma, the chloroplast shifts to a pathway that anomalously excludes the production of:

    • A) Non-cyclic photophosphorylation
    • B) Cyclic photophosphorylation
    • C) Photolysis
    • D) Calvin cycle

    Answer: Cyclic photophosphorylation

    Explanation: Cyclic photophosphorylation produces only ATP, no NADPH or O2. Non-cyclic is tempting as it produces all three components.
