Duba wurin da ke ƙasa sannan ka amsa tambayar daga baya a cikin harshe ɗaya kamar yadda wurin yake:  Passage: Photosynthesis shine haɗin carbohydrates daga hasken rana da carbon dioxide (CO2). 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 aikin photosynthetic, kamar yadda aka bayyana a sama, don canza CO2 zuwa glycerate 3-phosphate, wanda za'a iya canzawa zuwa glucose. Ana aiwatar da wannan aikin gyaran carbon ta hanyar enzyme RuBisCO a matsayin wani ɓangare na sake zagayowar Calvin <unk> Benson. Nau'i uku na photosynthesis suna faruwa a cikin tsire-tsire, C3 carbon fixation, C4 carbon fixation da CAM photosynthesis. Waɗannan sun bambanta da hanyar da carbon dioxide ke ɗauka zuwa zagayen Calvin, tare da tsire-tsire C3 suna gyara CO2 kai tsaye, yayin da C4 da CAM photosynthesis suka haɗa CO2 zuwa wasu mahaɗan da farko, azaman dacewa don ma'amala da tsananin hasken rana da yanayin bushewa. A cikin prokaryotes na photosynthetic hanyoyin haɗin carbon sun fi bambanci. A nan, za a iya gyara carbon dioxide ta hanyar Calvin <unk> Benson sake zagayowar, sake zagayowar citric acid, ko carboxylation na acetyl-CoA. Prokaryotic chemoautotrophs kuma gyara CO2 ta hanyar Calvin <unk> Benson sake zagayowar, amma amfani da makamashi daga inorganic mahadi don fitar da dauki.  Tambaya: Wace irin kwayar halitta ce ke da tsarin photosynthesis?
