Hauv eukaryotes, ib qho tseem ceeb electron thauj saw muaj 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.
Cov neeg kuj nug, dab tsi yog cov cab kuj nyob rau hauv lub electron thauj saw?
Cov Lus Qhia: Cov saw hlau thauj hluav taws xob (ETC) yog cov neeg siv khoom loj ntawm O2 hauv cov tsiaj txhu. Lub ETC kis electrons los ntawm NADH thiab FADH2 rau protein complexes thiab mobile electron cab kuj. Coenzyme Q (CoQ) thiab cytochrome c (Cyt c) yog mobile electron cab kuj nyob rau hauv ETC, thiab O2 yog zaum kawg electron txais.
Ib yam li ntawd, cov saw hlau thauj electron nyob qhov twg hauv daim duab ntawm mitochondrion hauv qab no? Cov electron thauj saw yog nyob nyob rau hauv lub puab membrane ntawm lub mitochondria , raws li qhia hauv qab no . Cov electron thauj saw muaj ib tug xov tooj ntawm hluav taws xob cov cab kuj. Cov cab kuj coj cov electrons los ntawm NADH thiab FADH2, hla lawv mus saw hlau ntawm complexes thiab hluav taws xob cov neeg nqa khoom, thiab thaum kawg tsim ATP.
Tsuas yog li ntawd, qhov twg cov protons tuaj ntawm hauv electron thauj saw?
Cov electron thauj saw yog ib tug series ntawm hluav taws xob transporters embedded nyob rau hauv lub puab mitochondrial membrane uas shuttles electrons los ntawm NADH thiab FADH2 rau molecular oxygen. Hauv cov txheej txheem, protons yog pumped los ntawm mitochondrial matrix mus rau qhov chaw intermembrane, thiab cov pa oxygen raug txo kom tsim dej.
Muaj pes tsawg ATP raug tsim nyob rau hauv cov saw hlau thauj electron?
34 TSI
Pom zoo:
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 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 khoom ntawm electron thauj saw?
Cov khoom kawg ntawm cov saw hlau thauj khoom yog dej thiab ATP. Ntau qhov sib xyaw nruab nrab ntawm lub voj voog citric acid tuaj yeem hloov mus rau hauv anabolism ntawm lwm cov biochemical molecules, xws li cov amino acids tsis tseem ceeb, suab thaj, thiab lipids
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
Qhov twg electron thauj saw nyob rau hauv cellular respiration?
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
