A cikin tsire-tsire, cyanobacteria da algae, oxygenic photosynthesis ya raba ruwa, tare da oxygen da aka samar a matsayin samfurin sharar gida. Wannan tsari yana amfani da ATP da NADPH da aka samar ta cibiyoyin amsawar hotuna, kamar yadda aka bayyana a sama, don canza CO2 zuwa glycerate 3-phosphate, wanda za'a iya canzawa zuwa glucose. Wannan aikin gyaran carbon-fixation ana aiwatar da shi ta hanyar enzyme RuBisCO a matsayin wani ɓangare na Calvin <unk> Benson sake zagayowar. Nau'i uku na photosynthesis suna faruwa a cikin tsire-tsire, C3 carbon fixation, C4 carbon fixation da CAM photosynthesis.
