  1. Question 1

    Q1. In the Calvin cycle, for every three molecules of CO2 fixed, how many molecules of G3P are net exported for glucose synthesis?

    • A) 1 G3P
    • B) 3 G3P
    • C) 5 G3P
    • D) 6 G3P

    Answer: 1 G3P

    Explanation: Only one G3P molecule per three CO2 fixed exits the cycle; five G3P must remain to regenerate RuBP.
