Dej , thaum tawg, ua rau oxygen, hydrogen, thiab electrons. Cov electrons txav los ntawm cov qauv hauv chloroplasts thiab los ntawm chemiosmosis, ua ATP . Cov hydrogen hloov mus rau NADPH uas yog tom qab ntawd siv rau hauv cov tshuaj tiv thaiv lub teeb. Oxygen diffuses tawm ntawm cov nroj tsuag raws li cov khoom pov tseg ntawm photosynthesis.

Ntxiv mus, dab tsi yog cov khoom ntawm lub teeb nyob rau hauv cov kev tshwm sim?

Cov khoom ntawm lub teeb-dependent cov tshuaj tiv thaiv, ATP thiab NADPH , yog ob qho tib si yuav tsum tau rau endergonic (def) lub teeb-yooj yim kev xav. Lub teeb-dependent tshwm sim muaj ob lub photosystems hu ua Photosystem I thiab Photosystem II.

Tom qab ntawd, lo lus nug yog, puas yog cov pa oxygen yog cov khoom ntawm lub teeb nyob ntawm qhov tshwm sim? Kev piav qhia: Oxygen yog nyob rau hauv qhov tseeb ib los ntawm cov khoom ntawm lub teeb nyob ntawm cov tshuaj tiv thaiv ntawm photosynthesis. Yog li ib qho enzyme rho tawm electron los ntawm dej, faib cov dej molecule rau hauv ob lub hydrogen ions thiab ib qho. oxygen atom. Cov oxygen atom abrubptly ua ke nrog lwm tus oxygen atom ua O2.

Qhov thib ob, yuav ua li cas rau cov pa oxygen uas tsim los ntawm lub teeb nyob ntawm qhov tshwm sim?

Hauv teeb - raws li kev xav , uas tshwm sim ntawm thylakoid daim nyias nyias, chlorophyll absorbs lub zog los ntawm lub hnub ci thiab tom qab ntawd hloov mus rau hauv tshuaj siv zog nrog kev siv dej. Cov teeb - raws li kev xav tso tawm oxygen raws li ib tug byproduct li dej yog sib cais.

Dab tsi yog 3 cov khoom ntawm lub teeb nyob ntawm qhov kev xav?

Hauv photosynthesis, chlorophyll, dej, thiab carbon dioxide yog reactants. GA3P thiab oxygen yog cov khoom . Hauv photosynthesis, dej, carbon dioxide, ATP, thiab NADPH yog reactants. RUBP thiab oxygen cov khoom.
