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.

Ob theem tseem ceeb ntawm photosynthesis yog dab tsi thiab txhua theem tshwm sim nyob qhov twg?
Ob theem ntawm photosynthesis: Photosynthesis yuav siv sij hawm qhov chaw nyob rau hauv ob theem: lub teeb-dependent kev tshwm sim thiab lub Calvin voj voog (lub teeb-yooj yim kev xav). Lub teeb-nyob ntawm cov tshuaj tiv thaiv, uas tshwm sim hauv thylakoid daim nyias nyias, siv lub teeb lub zog los ua ATP thiab NADPH
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
Mitochondrial oxidative phosphorylation yog dab tsi?
Oxidative phosphorylation (UK /?kˈs?d. ?. s?ˌde?. t?v/ lossis electron transport-linked phosphorylation) yog txoj hauv kev uas cov hlwb siv cov enzymes los oxidize cov as-ham, yog li tso tawm lub zog uas siv los tsim adenosine. triphosphate (ATP). Hauv feem ntau eukaryotes, qhov no tshwm sim hauv mitochondria
