Answer and explanation

Correct answer: A. Glycerate 3-phosphate (GP), formed when carbon dioxide combines with RuBP using rubisco

  1. Step 1: Rubisco joins CO2 to RuBP. Step 2. The unstable 6C compound splits into two molecules of GP. Answer: glycerate 3-phosphate. Why not the others: these are later products or the starting compound.
