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.

Dab tsi yog thawj kauj ruam ntawm proton proton saw?
Proton-proton chain reaction. Thawj kauj ruam nyob rau hauv tag nrho cov ceg yog fusion ntawm ob protons rau hauv deuterium. Raws li cov protons fuse, ib tug ntawm lawv undergoes beta ntxiv rau lwj, hloov mus rau hauv ib tug neutron los ntawm emitting ib tug positron thiab ib tug electron neutrino
Dab tsi yog cov reactants thiab cov khoom ntawm electron thauj saw hauv cellular respiration?
Lub ntsiab biochemical reactants ntawm ETC yog cov electron pub succinate thiab nicotinamide adenine dinucleotide hydrate (NADH). Cov no yog tsim los ntawm cov txheej txheem hu ua citric acid voj voog (CAC). Cov rog thiab suab thaj tau tawg mus rau hauv cov molecules yooj yim xws li pyruvate, uas tom qab ntawd pub rau hauv CAC
Dab tsi yog cov kauj ruam los daws qhov tsis sib xws ntawm ob kauj ruam?
Nws yuav siv ob kauj ruam los daws qhov kev sib npaug lossis qhov tsis sib xws uas muaj ntau tshaj ib qho kev ua haujlwm: Simplify siv qhov sib txawv ntawm qhov sib ntxiv lossis rho tawm. Ua kom yooj yim ntxiv los ntawm kev siv qhov sib txawv ntawm qhov sib npaug lossis faib
Koj ua li cas electron configuration kauj ruam yog kauj ruam?
Cov kauj ruam Nrhiav koj tus lej atomic. Txiav txim siab tus nqi ntawm lub atom. Nco cov npe ntawm cov orbitals. Nkag siab txog kev teeb tsa hluav taws xob. Nco qhov kev txiav txim ntawm lub orbitals. Sau rau hauv lub orbitals raws li tus naj npawb ntawm electrons hauv koj lub atom. Siv lub sij hawm ntev raws li qhov pom kev luv luv
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
