  1. Question 1

    Q1. During the Calvin cycle, 6 CO2 molecules are used to produce 12 molecules of G3P. How many G3P molecules are exported for glucose synthesis?

    • A) 12 G3P
    • B) 2 G3P
    • C) 6 G3P
    • D) 10 G3P

    Answer: 2 G3P

    Explanation: Two G3P molecules are exported to synthesize one glucose; ten are recycled. Twelve is wrong because the cycle would stop without RuBP regeneration.
