NADH yog daim ntawv txo ntawm electron cab kuj , thiab NADH hloov mus rau NAD+. Qhov no ib nrab ntawm tus kev tshwm sim tshwm sim hauv tus oxidation ntawm electron cab kuj.

Tsis tas li ntawd, dab tsi yog ib qho piv txwv ntawm cov khoom siv hluav taws xob electron molecule?

Ib electron cab kuj yog a molecule uas thauj electrons thaum ua pa ntawm tes. NAD yog ib electron cab kuj siv los khaws lub zog ib ntus thaum lub sijhawm ua pa ntawm tes. Lub zog no yog khaws cia los ntawm kev txo cov tshuaj tiv thaiv NAD + + 2H NADH + H +.

Kuj Paub, dab tsi yog cov khoom siv hluav taws xob? electron cab kuj . Ib qho ntawm ntau yam molecules uas muaj peev xwm lees txais ib lossis ob electrons los ntawm ib tug molecule thiab pub lawv mus rau lwm tus nyob rau hauv tus txheej txheem ntawm hluav taws xob thauj. Raws li cov electrons raug pauv los ntawm ib qho electron cab kuj rau lwm tus, lawv lub zog theem qis, thiab lub zog raug tso tawm.

Tsuas yog li ntawd, dab tsi yog txo cov neeg nqa hluav taws xob?

Ib tug xov tooj ntawm molecules yuav ua raws li cov khoom siv hluav taws xob nyob rau hauv biological systems. NAD+ txais ib hydrogen ion (H+) thiab ob electrons (2 e), raws li nws ua txo rau NADH + H+. NADH tsiv mus rau lub hluav taws xob thauj saw thiab pub ib khub ntawm electrons (ua oxidized) rau thawj qhov sib xyaw hauv cov saw hlau.

Dab tsi yog 3 electron cab kuj?

Oxidation-txo cov tshuaj tiv thaiv ib txwm tshwm sim hauv cov khub sib tw; tsis muaj molecule tuaj yeem oxidized tshwj tsis yog lwm qhov txo qis

  • Flavin Adenine Dinucleotide. Flavin adenine dinucleotide, los yog FAD, muaj riboflavin txuas rau adenosine diphosphate molecule.
  • Nicotinamide Adenine Dinucleotide.
  • Coenzyme Q.
  • Cytochrome C.
