Cov muaj nuj nqi ntawm electron thauj saw 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 khoom siv tshuab ua haujlwm rau hauv tshuaj lom neeg los ntawm kev tsim ATP, uas muaj zog tshaj plaws. cellular cov tshuaj tiv thaiv.
Ib yam li ntawd ib tug yuav nug, dab tsi yog lub hom phiaj tseem ceeb ntawm cov saw hlau thauj electron?
Cov Lub hom phiaj tseem ceeb 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, lub hom phiaj ntawm electron thauj saw hauv photosynthesis yog dab tsi? Electron Transport hauv Photosynthesis . Kev thauj khoom hluav taws xob pab tsim kom muaj ib qho proton gradient uas powers ATP ntau lawm thiab tseem khaws lub zog hauv cov coenzyme NADPH txo. Lub zog no yog siv los ua lub zog Calvin Cycle los tsim cov suab thaj thiab lwm yam carbohydrates.
Ntawm no, cov saw hlau thauj electron ua haujlwm li cas?
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. Nyob rau hauv tus txheej txheem, protons yog pumped los ntawm lub mitochondrial matrix mus rau lub intertermembrane qhov chaw, thiab oxygen yog txo mus rau hauv 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 qhov txawv ntawm daim ntawv qhia lub hom phiaj thiab daim ntawv qhia lub hom phiaj tshwj xeeb?
Qhov tseem ceeb hauv daim ntawv qhia dav dav yog nyob ntawm qhov chaw. Phab ntsa daim duab qhia chaw, feem ntau daim ntawv qhia pom nyob rau hauv atlases, thiab txoj kev maps yog tag nrho cov nyob rau hauv qeb no. Thematic maps, tseem hu ua daim ntawv qhia tshwj xeeb, qhia txog thaj chaw faib khoom ntawm ib lub ntsiab lus lossis qhov tshwm sim
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
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
