…CO₂ with the five-carbon sugar ribulose 1,5-bisphosphate (RuBP) in a series of reactions called the Calvin-Benson cycle. This reaction yields an unstable six-carbon intermediate, which immediately breaks down into two molecules of phosphoglycerate (PGA), a three-carbon acid. Each reaction is catalyzed by a specific enzyme. Six revolutions of the cycle…
