Kev txo qis Nws cuam tshuam nrog ib nrab-reactions nyob rau hauv uas ib hom tshuaj txo nws cov oxidation tooj, feem ntau yog los ntawm kev txais electrons. Ntawm no, oxidation yog qhov poob ntawm hydrogen, thaum txo yog qhov nce ntawm hydrogen. Qhov tseeb tshaj plaws txo Cov ntsiab lus suav nrog electrons thiab oxidation tooj.

Ua raws li qhov kev pom no, dab tsi yog qhov txo qis hauv biology?

Ib qho oxidation tshuaj tiv thaiv strips ib tug electron los ntawm ib tug atom nyob rau hauv ib tug compound, thiab ntxiv ntawm no electron mus rau lwm lub compound yog a txo cov tshuaj tiv thaiv . Vim oxidation thiab txo feem ntau tshwm sim ua ke, cov khub ntawm cov tshuaj tiv thaiv hu ua oxidation txo cov tshuaj tiv thaiv , los yog cov tshuaj tiv thaiv redox.

Ib yam li ntawd, txoj kev txo qis ua li cas? Kev txo qis yog tus txheej txheem ntawm ib tug atom los yog compound tau txais ib los yog ntau dua electrons. Thaum lub atom los yog compound tau txais ib qho hluav taws xob, nws cov nqi tau txais txo . Cov txheej txheem ntawm txo yog yuav luag ib txwm ua ke nrog cov txheej txheem ntawm oxidation . Ua ke, cov tshuaj tiv thaiv no yog hu ua oxidation - txo cov tshuaj tiv thaiv, los yog cov tshuaj tiv thaiv redox.

Hauv qhov no, qhov kev txo qis yog dab tsi muab piv txwv?

Ib piv txwv ntawm a txo yog thaum hlau reacts nrog oxygen, tsim hlau oxides (feem ntau hu ua xeb). Hauv qhov ntawd piv txwv , hlau yog oxidized thiab cov pa oxygen txo . Qhov no hu ua redox. Lub qhov cub tawg thim rov qab cov tshuaj tiv thaiv, siv cov pa roj carbon monoxide ua ib qho txo tus neeg sawv cev los txo cov hlau.

Dab tsi yog oxidation hauv biology?

Oxidation . Txhais. npe. (1) Kev sib xyaw ua ke ntawm cov pa oxygen nrog cov khoom tsim oxide. (2) Cov tshuaj tiv thaiv tshuaj uas muaj qhov poob ntawm electrons los yog nce (los yog nce hauv qhov sib piv) ntawm oxygen, yog li ntawd, ua rau muaj kev nce hauv oxidation lub xeev los ntawm ib tug molecule, atom los yog ion.
