Hauv electron thauj saw , electrons tau dhau los ntawm ib qho molecule mus rau lwm qhov, thiab lub zog tso tawm hauv cov no hluav taws xob hloov tsheb yog siv los ua ib qho electrochemical gradient. Hauv chemiosmosis, lub zog khaws cia hauv gradient yog siv ua ATP.
Ua raws li qhov no hauv kev txiav txim siab, puas yog ib qho ATP siv hauv cov saw hlau thauj hluav taws xob?
Tsis muaj ATP yog tsim nyob rau hauv lub electron thauj saw . Lub npe ntawm cov protein embedded uas muab cov channel rau hydrogen ions kom dhau los ntawm daim nyias nyias yog ATP synthase. Kev khiav ntawm hydrogen ions los ntawm cov protein channel muab lub zog pub dawb los ua haujlwm.
Kuj Paub, muaj pes tsawg ATP raug tsim nyob rau hauv electron thauj saw? 32 TSI
Ntawm no, yuav ua li cas ATP yog tsim nyob rau hauv lub electron thauj saw?
Cov txheej txheem ntawm kev tsim ATP los ntawm electron thauj saw yog hu ua oxidative phosphorylation. Hluav taws xob nqa los ntawm NADH + H+ thiab FADH2 yog pauv mus rau oxygen ntawm ib tug series ntawm hluav taws xob cov cab kuj, thiab ATPs yog tsim . Peb ATPs yog tsim los ntawm txhua NADH + H+, thiab ob ATPs yog tsim rau txhua FADH2 hauv eukaryotes.
Dab tsi reactant yog siv nyob rau hauv electron thauj saw?
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 thawj kauj ruam hauv cov saw hlau thauj electron?
Cov saw hlau thauj khoom siv hluav taws xob siv cov khoom lag luam los ntawm thawj ob txoj haujlwm 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
Dab tsi yog kev siv cov saw hlau nuclear siv rau?
Nuclear chain reaction. Nuclear chain reactions yog cov tshuaj tiv thaiv uas tau txais lub zog nuclear, feem ntau los ntawm nuclear fission. Cov kev cuam tshuam ntawm cov saw hlau no yog qhov muab cov chaw tsim hluav taws xob nuclear nrog lub zog uas tom qab ntawd hloov mus ua hluav taws xob siv los ntawm tib neeg
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
Cov neeg nqa khoom ntawm cov saw hlau thauj electron nyob qhov twg?
Nyob rau hauv eukaryotes, ib qho tseem ceeb electron thauj saw yog pom nyob rau hauv lub puab mitochondrial membrane qhov twg nws ua hauj lwm raws li qhov chaw ntawm oxidative phosphorylation los ntawm kev ua ntawm ATP synthase. Nws kuj pom muaj nyob rau hauv thylakoid membrane ntawm chloroplast hauv photosynthetic eukaryotes
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
