Oxidative phosphorylation tshwm sim hauv ob kauj ruam : cov saw hlau thauj electron thiab chemiosmosis.

Ntawm no, dab tsi yog 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

Ib yam 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 yam li ntawd, tib neeg 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.

Puas yog NADH 2.5 lossis 3 ATP?

Yuav kom dhau cov electrons los ntawm NADH mus kawg Oxygen txais, tag nrho ntawm 10 protons raug thauj los ntawm matrix mus rau inter mitochondrial membrane. 4 protons ntawm complex 1, 4 ntawm complex 3 thiab 2 ntawm complex 4. Yog li rau NADH - 10/4= 2.5 TSI yog ua ua tau. Ib yam li ntawd rau 1 FADH2, 6 protons raug txav mus li 6/4 = 1.5 ATP yog ua.
