Cov khoom siv hluav taws xob muaj cov molecules tseem ceeb hauv cov kab mob lom. Lawv txais electrons thiab txav lawv los ua ib feem ntawm cov hluav taws xob thauj saw, hloov lub hluav taws xob , thiab lub zog nws sawv cev, kom lub zog ntawm tes. Cov khoom siv hluav taws xob muaj Qhov tseem ceeb ntawm kev ua pa ntawm tes thiab photosynthesis.

Hauv qhov no, cov khoom siv hluav taws xob yog dab tsi thiab lawv lub hom phiaj yog dab tsi?

Ib electron cab kuj yog 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 ntawm tus txo cov tshuaj tiv thaiv NAD + + 2H NADH + H +.

Tsis tas 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.

Ua raws li qhov kev pom no, dab tsi yog lub tshuab nqa 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.

Cov neeg nqa hluav taws xob mus qhov twg?

Cov cov khoom siv hluav taws xob coj cov electrons mus rau ib pab pawg neeg ntawm cov protein nyob rau hauv lub puab membrane ntawm lub mitochondrion, hu ua lub hluav taws xob thauj saw. Raws li electrons txav mus los ntawm hluav taws xob thauj saw, lawv mus los ntawm qhov siab dua mus rau qib qis zog thiab yog Thaum kawg kis mus rau oxygen (ua dej).
