Cov khoom kawg ntawm electron thauj saw 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.
Kuj paub, dab tsi yog cov khoom tsim los ntawm cov saw hlau thauj khoom?
Hluav taws xob Cov cab kuj raug txo thaum lub sij hawm glycolysis thiab citric acid voj voog rau NADH + H + thiab FADH2. Cov neeg nqa khoom no ces pub dawb electrons thiab cov protons mus rau qhov hluav taws xob carrier proteins ntawm cov hlab ntsha electron thauj saw . Qhov kawg hluav taws xob txais yog oxygen. Ua ke nrog oxygen, electrons thiab protons tsim molecules ntawm dej.
Ib sab saum toj no, lub hom phiaj ntawm cov saw hlau thauj electron yog dab tsi? Lub ntsiab Lub hom phiaj ntawm cov saw hlau thauj electron yog tsim kom muaj qhov seem ntawm hydrogen ions (protons) nyob rau hauv qhov chaw interemembrane thiaj li yuav muaj qhov concentration gradient piv rau cov matrix ntawm mitochondria.
Tsis tas li ntawd, cov khoom thiab cov reactants ntawm electron thauj saw yog dab tsi?
Cov ntsiab lus hauv cov teeb no (10)
- Reactants thiab cov khoom ntawm ETC. Electron Transport reactants: Hydrogen ions, oxygen, NADH, FADH2 Khoom: Dej thiab ATP (2 e- + 2 H + 1/2 O2 = H20)
- Complex I. NADH dehydrogenase.
- Complex II.
- Complex III.
- Complex IV.
- Lub luag haujlwm ntawm Oxygen hauv ETC.
- Phosphorylation ntawm substrate.
- Oxidative Phosphorylation.
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
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
Lub hom phiaj ntawm electron thauj saw hauv cellular respiration yog dab tsi?
Kev ua haujlwm ntawm cov saw hlau thauj hluav taws xob yog los tsim cov transmembrane proton electrochemical gradient raws li qhov tshwm sim ntawm cov tshuaj tiv thaiv redox. ATP synthase, ib qho enzyme uas tau txais txiaj ntsig zoo ntawm txhua lub neej ntawm lub neej, hloov cov kev ua haujlwm no rau hauv cov tshuaj lom neeg los ntawm kev tsim cov ATP, uas ua rau muaj kev cuam tshuam ntau ntawm cov cellular
