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.
Tom qab ntawd, ib tug kuj yuav nug, dab tsi yog cov reactants thiab cov khoom ntawm electron thauj saw?
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.
Ib yam li ntawd, dab tsi yog cov reactants thiab cov khoom ntawm cellular respiration? Kev ua pa ntawm tes yog cov txheej txheem ua lub luag haujlwm rau kev hloov tshuaj lub zog, thiab cov reactants / cov khoom koom nrog hauv kev ua pa ntawm tes yog oxygen , qabzib ( qab zib ), carbon dioxide , thiab dej.
Tsis tas li ntawd, cov khoom ntawm electron thauj saw hauv cellular respiration yog dab tsi?
Cellular Respiration Summary Thaum kawg, nyob rau hauv electron thauj saw, cov khoom siv hluav taws xob tau siv los pub cov electrons thiab protons uas hloov oxygen molecules rau hauv. dej thiab tsim cov seem ntawm 32 ATP molecules - tag nrho los ntawm ib qho qabzib molecule.
Dab tsi yog inputs thiab outputs ntawm electron thauj saw?
Cov nkag ntawm electron thauj saw yog NADH+FADH2. Cov tso zis yuav yog 34 lossis 36 ATP. Muaj lub sijhawm thaum cov electron thauj saw muaj txiaj ntsig kom tau txais lub zog los ntawm qee qhov xwm txheej. Piv txwv li, qhov no tshwm sim thaum lub sij hawm photosynthesis thaum tshav ntuj mus txog cov nroj tsuag.

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
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
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
