Geedi socodkan wuxuu isticmaalaa ATP iyo NADPH oo ay soo saaraan xarumaha falcelinta fotosynthetic, sida kor lagu sharaxay, si loogu beddelo CO2 glycerate 3-phosphate, kaas oo markaa loo rogi karo gulukoos. Isbeddelkan ku-xirnaanta kaarboonka waxaa fuliya enzyme RuBisCO oo qayb ka ah wareegga Calvin <unk> Benson. Saddex nooc oo ah sawir-qaadista ayaa ka dhaca dhirta, C3 kaarboonka, C4 kaarboonka iyo sawir-qaadista CAM. Waxay ku kala duwan yihiin wadada kaarboonka ee wareegga Calvin, iyadoo C3 si toos ah loogu daro CO2, halka C4 iyo CAM2 ay ku jiraan isku-darka sawir-qaadista oksijiinta, iyadoo oksijiinta loo soo saaro badeecad qashinka ah.
