Nyob rau hauv no series ntawm cov tshuaj tiv thaiv , electron yog ua ntej hla mus a protein ntau hu ua ferredoxin (Fd), ces pauv mus rau ib qho enzyme hu ua NADP + pib superscript, ntxiv rau, kawg superscriptreductase.
Tsuas yog li ntawd, qhov twg electrons tuaj ntawm lub teeb nyob rau hauv cov kev tshwm sim?
Hauv (b) photosystem I, the hluav taws xob los ntawm chloroplast hluav taws xob thauj saw. Ob lub photosystems nqus teeb lub zog los ntawm cov protein uas muaj cov xim, xws li chlorophyll. Cov teeb - raws li kev xav pib hauv photosystem II.
Qhov thib ob, dab tsi tshwm sim thaum 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. Tom qab lub zog tso tawm, cov "kho" lub zog nqa rov qab mus rau qhov teeb - raws li kev xav kom tau txais lub zog ntau dua.
Cov neeg kuj nug, 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.
Dab tsi yog 7 kauj ruam ntawm lub teeb nyob ntawm qhov tshwm sim?
Cov ntsiab lus hauv cov teeb no (7)
- (Lub Sij Hawm 1) Lub zog yog nqus los ntawm lub hnub.
- Dej tawg lawm.
- Hydrogen ions raug thauj mus los ntawm thylakoid membrane.
- (Lub Sij Hawm thib 2) Lub zog yog nqus los ntawm lub hnub.
- NADPH yog tsim los ntawm NADP +.
- Hydrogen ions diffuse los ntawm cov protein channel.
