Tsis-Cyclic Photophosphorylation
Cov hluav taws xob los ntawm PS I kuj tseem tuaj yeem dhau mus rau cov khoom siv hluav taws xob thiab tom qab ntawd ua ke nrog hydrogen ions (los ntawm dej) kom txo tau NADP rau NADPH. Qhov no txo NADP yog siv nyob rau hauv lub tom ntej series ntawm cov tshuaj tiv thaiv.
Ua raws li qhov no, yuav ua li cas txo NADP siv nyob rau hauv lub teeb ywj siab tshuaj tiv thaiv?
Glycerate 3-phosphate (GP) hloov mus rau hauv triose phosphate (TP) siv txo NADP thiab ATP. Cov txo NADP muab cov txo fais fab (hydrogen) thiab hloov dua siab tshiab rau NADP uas yog ces txo dua hauv teeb - raws li kev xav . ATP kuj yog siv muab lub zog rau kev hloov dua siab tshiab.
Ib sab saum toj no, dab tsi txo qis hauv lub teeb nyob ntawm qhov tshwm sim? Cov teeb - raws li kev xav siv teeb lub zog los ua ob lub molecules xav tau rau theem tom ntej ntawm photosynthesis: lub zog cia molecule ATP thiab txo electron cab kuj NADPH. Hauv cov nroj tsuag, cov teeb pom kev zoo Nyob rau hauv lub thylakoid daim nyias nyias ntawm organelles hu ua chloroplasts.
Tom qab ntawd, lo lus nug yog, NADP txo qis li cas?
Electron Transport Chain Hydrogen ions yog thauj nrog cov electrons raws cov saw ntawm cov tshuaj tiv thaiv. Thaum cov tshuaj tiv thaiv no, cov NADP + molecules yog txo los ntawm kev sib ntxiv ntawm electrons. Ib qho hydrogen ion yog ntxiv rau NADP + tsim NADPH.
Yuav ua li cas tshwm sim rau cov electrons nyob rau hauv lub teeb nyob rau hauv cov kev tshwm sim ntawm photosynthesis?
Teeb - nyob ntawm cov tshuaj tiv thaiv . Hauv photosynthesis , cov teeb - nyob ntawm cov tshuaj tiv thaiv siv teeb lub zog los ntawm lub hnub los faib dej (photolysis). Dej, thaum tawg, ua rau oxygen, hydrogen, thiab electrons . Cov no electrons txav los ntawm cov qauv hauv chloroplasts thiab los ntawm chemiosmosis, ua ATP.

Vim li cas cov tshuaj tiv thaiv kev zom zaub mov hu ua hydrolysis cov tshuaj tiv thaiv?
Thaum lub sij hawm zom mov, piv txwv li, decompositionreactions zom cov zaub mov loj rau hauv cov me me los ntawm kev ntxiv cov dej molecules. Hom tshuaj no hu ua hydrolysis. Raws li dej absorbs heatenergy, qee lub zog yog siv los rhuav tshem hydrogenbonds
Dab tsi yog thawj cov protein complex koom nrog hauv cov tshuaj tiv thaiv lub teeb?
Nyob rau hauv cov kev tshwm sim no, cov electron yog thawj zaug kis mus rau ib qho protein hu ua ferredoxin (Fd), ces pauv mus rau ib qho enzyme hu ua NADP + pib superscript, ntxiv rau, kawg superscriptreductase
Cov tshuaj tiv thaiv zoo li cas thaum cov tshuaj nkag mus rau hauv cov hlab ntsha?
Cov tshuaj tiv thaiv 'systemic' tshwm sim thaum cov tshuaj nkag mus rau hauv cov hlab ntsha los ntawm daim tawv nqaij, qhov muag, qhov ncauj, lossis lub ntsws
Cov tshuaj tiv thaiv dab tsi yog qhov tshuaj tiv thaiv neutralization?
Neutralization yog ib hom tshuaj tiv thaiv nyob rau hauv uas muaj zog acid thiab muaj zog puag react nrog ib leeg los tsim dej thiab ntsev
Dab tsi yog tshuaj lom neeg cov tshuaj tiv thaiv thiab cov tshuaj tiv thaiv lub cev?
Qhov sib txawv ntawm cov tshuaj tiv thaiv lub cev thiab cov tshuaj tiv thaiv tshuaj yog muaj pes tsawg leeg. Hauv cov tshuaj tiv thaiv tshuaj, muaj kev hloov pauv ntawm cov tshuaj hauv nqe lus nug; nyob rau hauv ib qho kev hloov ntawm lub cev muaj qhov sib txawv ntawm qhov tsos, tsis hnov tsw, los yog cov duab yooj yim ntawm cov qauv ntawm cov teeb meem yam tsis muaj kev hloov pauv hauv cov ntsiab lus
