  1. Question 1

    Q1. When Rubisco functions as an oxygenase, it breaks RuBP into one molecule of 3-PGA and one molecule of which two-carbon compound?

    • A) Phosphoglycolate
    • B) Glyceraldehyde-3-phosphate
    • C) Oxaloacetate
    • D) Pyruvate

    Answer: Phosphoglycolate

    Explanation: Oxygenation of RuBP produces one PGA and one phosphoglycolate. G3P is the normal product of the reductive Calvin cycle.
