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.

Vim li cas nws nyuaj rau pov tseg cov pov tseg nuclear?
Nuclear pov tseg yog ib qho nyuaj tshaj plaws ntawm cov pov tseg rau kev tswj hwm vim tias nws muaj kev phom sij heev. Vim nws cov xov tooj cua thiab cov khoom muaj kev phom sij heev, cov khib nyiab nuclear yuav tsum tau ua tib zoo khaws cia lossis rov ua dua
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 pov thawj ntawm cov tshuaj tiv thaiv tshuaj?
Kev hloov xim, tsim los ntawm precipitate lossis roj, lossis qhov kub thiab txias yog cov pov thawj ntawm cov tshuaj tiv thaiv
Dab tsi yog cov khoom pov tseg ntawm cov saw hlau thauj khoom?
Yog tias muaj cov pa oxygen, kev ua pa ntawm tes hloov lub zog los ntawm ib qho molecule ntawm qabzib mus rau 38 molecules ntawm ATP, tso carbon dioxide thiab dej pov tseg
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
