The molecule that forms splits into two molecules of PGA. • Each PGA gets a phosphate group from ATP and electrons from NADPH. The resulting intermediate, PGAL, is primed for a reaction. • After six molecules of carbon dioxide have been fixed, 12 PGAL form. • Two of the PGAL molecules combine to form the six-carbon sugar glucose. The glucose will enter other reactions that form carbohydrates. • The remaining 10 PGAL get phosphate groups from ATP. This primes them for the reactions that regenerate RuBP, thus completing the cycle.
