2. Sugar is made in the chloroplast through CO2 assimilation by the Calvin cycle. This cycle involves 11 enzymes and produces carbohydrates from atmospheric CO2 using NADPH and ATP supplied by the light reactions. Chloroplast phosphoglycerate kinase (cpPGK) catalyzes the conversion of 3-phosphoglycerate to 1,3-bisphosphoglycerate using ATP (step #2).
