  1. Question 1

    Q1. Researchers provide a chloroplast suspension with ATP, NADPH, and CO2 in total darkness. Which biosynthetic process will proceed normally?

    • A) Photolysis of water
    • B) Cyclic photophosphorylation
    • C) Carbon dioxide fixation
    • D) Non-cyclic electron flow

    Answer: Carbon dioxide fixation

    Explanation: Calvin Cycle requires ATP and NADPH from light reactions; light-dependent reactions are tempting but they produce these molecules instead.
