Oxidative phosphorylation (UK /?kˈs?d. ?. s?ˌde?. t?v/ lossis electron transport-linked phosphorylation ) yog txoj hauv kev metabolic uas cov hlwb siv cov enzymes los oxidize cov as-ham, yog li tso lub zog uas siv los tsim adenosine triphosphate (ATP). Hauv feem ntau eukaryotes, qhov no tshwm sim hauv mitochondria.
Tsuas yog li ntawd, oxidative phosphorylation yog dab tsi thiab nws tshwm sim qhov twg?
Oxidative phosphorylation yog ib tug mechanism rau ATP synthesis nyob rau hauv cov nroj tsuag thiab tsiaj hlwb. Nws suav nrog chemiosmotic coupling ntawm electron thauj thiab ATP synthesis. Oxidative phosphorylation tshwm sim hauv mitochondria. Lub mitochondrion muaj ob daim nyias nyias: ib daim nyias nyias thiab ib daim nyias nyias.
Ib tug kuj yuav nug, dab tsi yog cov theem ntawm oxidative phosphorylation? Peb qhov loj cov kauj ruam hauv oxidative phosphorylation yog (a) oxidation - txo cov kev cuam tshuam nrog kev hloov hluav taws xob ntawm cov protein tshwj xeeb uas kos rau hauv daim nyias nyias mitochondrial; (b) tiam ntawm proton (H+) gradient hla lub puab mitochondrial membrane (uas tshwm sim ib txhij nrog cov kauj ruam (a
Tib neeg kuj nug, dab tsi yog txhais los ntawm oxidative phosphorylation?
Txhais ntawm oxidative phosphorylation .: lub synthesis ntawm ATP los ntawm phosphorylation ntawm ADP uas lub zog tau txais los ntawm kev thauj khoom hluav taws xob thiab uas tshwm sim hauv mitochondria thaum lub sij hawm ua pa aerobic.
Dab tsi yog Uncouplers ntawm oxidative phosphorylation?
Ib uncoupler los yog uncoupling tus neeg sawv cev yog molecule uas cuam tshuam oxidative phosphorylation nyob rau hauv prokaryotes thiab mitochondria los yog photophosphorylation hauv chloroplasts thiab cyanobacteria los ntawm dissociating cov tshuaj tiv thaiv ntawm ATP synthesis los ntawm cov electron thauj saw.
Pom zoo:
Puas yog oxidative phosphorylation zoo ib yam li electron thauj saw?
Oxidative phosphorylation yog tsim los ntawm ob qho kev sib txuas zoo sib xws: cov saw hlau thauj hluav taws xob thiab chemiosmosis. Hauv cov khoom siv hluav taws xob thauj khoom, cov khoom siv hluav taws xob tau dhau los ntawm ib lub molecule mus rau lwm qhov, thiab lub zog tso tawm hauv cov hluav taws xob hloov hluav taws xob no yog siv los tsim cov tshuaj electrochemical gradient
Oxidative phosphorylation yog dab tsi thiab nws tshwm sim qhov twg?
Oxidative phosphorylation yog ib txoj hauv kev rau ATP synthesis hauv cov nroj tsuag thiab tsiaj txhu. Nws suav nrog chemiosmotic coupling ntawm electron thauj thiab ATP synthesis. Oxidative phosphorylation tshwm sim hauv mitochondria. Lub mitochondrion muaj ob daim nyias nyias: ib daim nyias nyias thiab ib daim nyias nyias
Dab tsi ua rau oxidative phosphorylation?
Oxidative phosphorylation yog cov txheej txheem uas ATP yog tsim raws li cov khoom siv hluav taws xob hloov pauv los ntawm cov ntaub ntawv txo qis ntawm nicotinamide adenine dinucleotide (NADH) thiab flavin adenine dinucleotide (FADH2) mus rau molecular oxygen (O2) los ntawm cov khoom siv hluav taws xob thauj khoom (xws li cov saw hlau thauj hluav taws xob. )
Dab tsi yog txhais los ntawm oxidative phosphorylation?
Lub ntsiab lus ntawm oxidative phosphorylation: lub synthesis ntawm ATP los ntawm phosphorylation ntawm ADP rau lub zog yog tau los ntawm electron thauj thiab uas tshwm sim nyob rau hauv lub mitochondria thaum lub sij hawm aerobic ua pa
Ob theem ntawm oxidative phosphorylation yog dab tsi?
Oxidative phosphorylation tshwm sim nyob rau hauv ob kauj ruam: electron thauj saw thiab chemiosmosis
