Rịba ama amaokwu a dị n'okpuru ma zaa ajụjụ ahụ mgbe e mesịrị n'otu asụsụ ahụ dị ka amaokwu ahụ:  Nkọwa: Usoro photosynthesis bụ njikọ nke carbohydrates site n'ìhè anyanwụ na carbon dioxide (CO2). N'ime ahịhịa, cyanobacteria na algae, photosynthesis oxygen na-ekewa mmiri, na ikuku oxygen emepụtara dị ka ngwaahịa mkpofu. Usoro a na-eji ATP na NADPH mepụtara site na ogige mmeghachi omume photosynthetic, dị ka akọwara n'elu, iji gbanwee CO2 n'ime glycerate 3-phosphate, nke enwere ike gbanwee n'ime glucose. A na-eme mmeghachi omume carbon-fixation a site na enzyme RuBisCO dị ka akụkụ nke Calvin <unk> Benson okirikiri. Ụdị atọ nke photosynthesis na-eme na osisi, C3 carbon fixation, C4 carbon fixation na CAM photosynthesis. Ndị a dị iche site n'ụzọ nke carbon dioxide na-ewere na Calvin okirikiri, na C3 osisi fixing CO2 ozugbo, mgbe C4 na CAM photosynthesis incorporate na CO2 n'ime ndị ọzọ ogige mbụ, dị ka mgbanwe obibi ike ìhè anyanwụ na akọrọ ọnọdụ. Na photosynthetic prokaryotes usoro nke carbon fixation bụ ndị ọzọ iche iche. N'ebe a, enwere ike idozi carbon dioxide site na Calvin <unk> Benson okirikiri, okirikiri citric acid gbanwere, ma ọ bụ carboxylation nke acetyl-CoA. Chemoautotrophs prokaryotic na-ejikwa CO2 site na Calvin <unk> Benson okirikiri, mana jiri ike sitere na inorganic compounds iji mee ka mmeghachi omume ahụ.  Ajụjụ: Olee ụdị ihe dị ndụ na-eme photosynthesis?
