O lenei faagasologa e faaaoga ai le ATP ma NADPH gaosia e le photosynthetic ogatotonu tali, e pei ona faamatalaina i luga, e liliu CO2 i glycerate 3-phosphate, lea e mafai ona liua i kulukose. O lenei carbon-faamautuina tali ua tauaveina e le enzyme RuBisCO o se vaega o le Calvin <unk> Benson taamilosaga. tolu ituaiga o photosynthesis tupu i laau, C3 carbon faʻamautuina, C4 carbon faʻamautuina ma CAM photosynthesis.
