C4 nroj tsuag loj bypass photorespiration photorespiration Photorespiration (tseem hu ua oxidative photosynthetic carbon cycle, los yog C2 photosynthesis) yog hais txog txheej txheem Nyob rau hauv cov nroj tsuag metabolismqhov twg enzyme RuBisCO oxygenates RuBP, nkim qee lub zog tsim los ntawm photosynthesis. … Photorespiration kuj ua rau tus nqi ncaj qha ntawm ib qho ATP thiab ib NAD(P)H. https://en.wikipedia.org › wiki › Photorespiration
Photospiration - Wikipedia
los ntawm kev siv qhov txuas ntxiv ntawm Calvin-Benson lub voj voog txhawm rau tso cov CO2, thiab tsis yog oxygen, rau hauv cov hnab ntim cell uas cov tshuaj tiv thaiv RUBISCO tshwm sim.
Pob C4 thiab CAM cov nroj tsuag siv lub voj voog Calvin?
C3 photosynthesis ua rau peb-carbon compound ntawm Calvin lub voj voog thaum C4 photosynthesis ua rau intermediate plaub-carbon compound uas splits rau hauv peb-carbon compound rau Calvin voj voog. Cov nroj tsuag uas siv CAM photosynthesis sau hnub ci thaum nruab hnub thiab kho cov pa roj carbon dioxide molecules thaum hmo ntuj.
Puas C4 siv Calvin lub voj voog?
C4 cov nroj tsuag tshwj xeeb vim lawv suav nrog lwm hom carbon fixation uas tsim tau plaub-carbon qab zib (li no lawv lub npe) ua ntej lawv mus rau Calvin lub voj voog. … Nyob rau hauv cov nroj tsuag C4, lub voj voog Calvin tshwm sim nyob rau hauv cov ntaub qhwv-sheath cells (hauv C3 cov nroj tsuag no tshwm sim hauv cov hlwb mesophyll).
C4 cov nroj tsuag puas siv Calvin voj voog rau kev kho cov pa roj carbon monoxide?
Nyob rau hauv txoj kev C4, pib cov pa roj carbon fixation tshwm sim nyob rau hauv mesophyll hlwb thiab lub Calvin voj voog tshwm sim nyob rau hauv bundle-sheath cells … Pyruvate kuj tsim nyob rau hauv cov kauj ruam no thiab txav rov qab mus rau hauv mesophyll cell, qhov twg nws hloov mus rau hauv PEP (ib qho tshuaj tiv thaiv uas hloov ATP thiab Pi rau hauv AMP thiab PPi).
Cov nroj tsuag twg siv lub voj voog Calvin?
Cov nroj tsuag uas siv tsuas yog Calvin lub voj voog rau kev kho cov pa roj carbon monoxide hu ua C3 nroj tsuag. Cov pa roj carbon dioxide diffuses mus rau hauv stroma ntawm chloroplasts thiab ua ke nrog tsib-carbon qab zib, ribulose1, 5-biphosphate (RuBP).
