Cov electron thauj saw siv cov khoom siv los ntawm cov khoom siv ua ntej ob qho kev ua ntawm glycolysis thiab citric acid voj voog kom tiav cov tshuaj tiv thaiv uas hloov peb cov zaub mov rau hauv lub zog siv tau ntawm tes.

Yog li ntawd, dab tsi yog cov kauj ruam hauv electron thauj saw?

Electron Transport Chain . Oxidative phosphorylation tshwm sim nyob rau ntau qhov sib txawv cov kauj ruam : Proton twj tsim ib qho electrochemical gradient (proton motive force) ATP synthase siv cov tom ntej diffusion ntawm protons (chemiosmosis) los ua ke ATP.

Qhov thib ob, dab tsi yog cov saw hlau thauj electron hauv cov ntsiab lus yooj yim? Cov electron thauj saw muaj ib tug series ntawm redox tshuaj tiv thaiv nyob rau hauv uas electrons tau pauv los ntawm tus neeg pub khoom molecule mus rau tus txais molecule. Lub hauv paus quab yuam tsav cov kev cuam tshuam no yog lub zog dawb (lub zog muaj los ua haujlwm) ntawm cov reactants thiab cov khoom.

Raws li txoj cai, dab tsi nkag mus thiab tawm ntawm cov saw hlau thauj electron?

2 CO2 thiab 2 ATP tawm tuaj , nrog rau 6 NADH, thiab 2 FADH2. Dab tsi mus mus rau hauv electron thauj saw ? Cov electrons "poob" txhawm rau tso H + hla ib daim nyias nyias, thiab H + tsim ATP thaum lawv hla rov qab. Nyob rau hauv photosynthesis, lub electron tuaj los ntawm dej; hauv kev ua pa, cov electron tuaj los ntawm zaub mov.

Yuav ua li cas thiaj li electrons txav los ntawm cov saw hlau thauj electron?

Nyob rau hauv lub mitochondrial electron thauj saw electrons txav los ntawm ib tug electron pub (NADH los yog QH2) mus rau lub davhlau ya nyob twg electron txais (O2) via a series ntawm redox cov tshuaj tiv thaiv. Cov tshuaj tiv thaiv no yog ua ke rau kev tsim cov proton gradient thoob plaws mitochondrial puab daim nyias nyias.
