Photosynthesis hauv cov nroj tsuag thiab cyanobacteria tsim ob qho tib si ATP thiab NADPH ncaj qha los ntawm ob-kauj ruam txheej txheem hu ua noncyclic photophosphorylationVim tias ob lub photosystems-hu ua photosystems I thiab II-yog siv nyob rau hauv series rau energize ib electron, lub electron yuav kis tau tag nrho txoj kev ntawm dej mus rau NADPH.

ATP ua kom zoo li cas thaum lub sijhawm photosynthesis?

Thaum lub sijhawm photosynthesis hauv cov nroj tsuag, ATP yog tsim los ntawm ATP synthase siv cov proton gradient tsim nyob rau hauv thylakoid lumen los ntawm thylakoid membrane thiab mus rau hauv chloroplast stroma … Ib qho F-ATPase muaj ntawm ob lub ntsiab subunits, F_O thiab F_{1, uas muaj kev sib hloov lub cev muaj zog tso cai rau ATP ntau lawm.}

YPuas photosynthesis koom nrog ATP synthesis?

Photosynthesis tshwm sim hauv ob theem sib txawv. Hauv lub teeb pom kev zoo, lub zog los ntawm lub hnub ci tsav lub synthesis ntawm ATP thiab NADPH, ua ke rau kev tsim ntawm O₂ los ntawm H _{2O. Nyob rau hauv qhov tsaus ntuj tshwm sim, thiaj li hu ua vim lawv tsis xav tau lub hnub ci, lub ATP thiab NADPH tsim los ntawm lub teeb tshwm sim tsav cov piam thaj synthesis.}

Qhov twg ntawm photosynthesis yog ATP tsim?

ATP thiab NADPH yog tsim los ntawm the stroma sab ntawm thylakoid membrane, qhov uas lawv tuaj yeem siv los ntawm Calvin cycle.

Nyob rau hauv cov txheej txheem twg yog cov synthesis ntawm ATP los ntawm Chemiosmotic mechanism nyob rau hauv photosynthetic nroj tsuag tshwm sim?

Yog, chemiosmosis tshwm sim hauv photosynthesis thiab ua pa. Thaum lub sij hawm photosynthesis, chemiosmosis tshwm sim nyob rau hauv chloroplasts, whereas thaum lub sij hawm ua pa, chemiosmosis tshwm sim nyob rau hauv lub mitochondria.
