Fe yog ib qho tseem ceeb ntawm cov proteins uas koom nrog kev hloov pauv ntawm electrons hloov ntawm electrons Electron transfer (ET) tshwm sim thaum ib qho hluav taws xob txav los ntawm ib qho atom lossis molecule mus rau lwm qhov chaw tshuaj lom neeg. … Tsis tas li ntawd, cov txheej txheem ntawm kev hloov hluav taws xob tuaj yeem ua tau raws li kev sib pauv ntawm ob-electron (ob qhov xwm txheej ET nyob rau hauv cov lus qhia sib txawv) nyob rau hauv rooj plaub me me ntawm cov khoom hloov pauv. https://en.wikipedia.org › wiki › Electron_transfer
Kev hloov hluav taws xob - Wikipedia
zoo li ferredox hauv thiab cytochromes. Nws yog reversibly oxidised los ntawm Fe2+ rau Fe3+thaum hloov hluav taws xob. Cu yog qhov tseem ceeb rau tag nrho cov metabolism hauv cov nroj tsuag.

Puas yog hlau ib txwm oxidized?
Vim Pab 1 cov hlau ib txwm muaj lub xeev oxidation ntawm +1 hauv lawv cov tebchaw, nws ua raws li cov hydrogen yuav tsum muaj lub xeev oxidation ntawm -1 (+1 -1=0). Peroxides muaj xws li hydrogen peroxide, H2O2. Qhov no yog cov khoom siv hluav taws xob tsis zoo thiab yog li cov txiaj ntsig ntawm oxidation xeev ntawm hydrogen thiab oxygen yuav tsum yog xoom.
