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.

Dab tsi yog ib txoj hauv kev uas koj tuaj yeem txo qhov kev sib txhuam ntawm ob qhov chaw?
Cov txheej txheem sib txawv tuaj yeem siv los txo qhov kev sib txhuam ntawm qhov chaw ntawm cov khoom hauv kev sib cuag. Ib txoj hauv kev los txo kev sib txhuam yog siv cov roj nplua nyeem rau qhov chaw, lwm qhov yog siv cov casters, rollers, lossis pob bearings nruab nrab ntawm qhov chaw, thiab lwm qhov yog ua kom du ntawm cov khoom hauv kev sib cuag
Dab tsi yog lub ntsiab lus ntawm kev txo qis hauv biology?
Kev txo qis suav nrog ib nrab ntawm cov tshuaj tiv thaiv uas ib hom tshuaj txo nws cov oxidation naj npawb, feem ntau yog los ntawm kev txais electrons. Ntawm no, oxidation yog qhov poob ntawm hydrogen, thaum txo qis yog qhov nce ntawm hydrogen. Qhov kev txo qhov tseeb tshaj plaws suav nrog cov electrons thiab oxidation tooj
Yuav txo qis hauv kev tshawb fawb li cas?
Txhawm rau txo qhov siab - txo qhov quab yuam los yog ua kom thaj tsam qhov quab yuam ua rau. Yog tias koj tau sawv ntawm lub pas dej khov thiab cov dej khov pib tawg koj tuaj yeem pw tsaug zog kom thaj chaw sib cuag nrog cov dej khov. Tib lub zog (koj qhov hnyav) yuav siv tau, kis mus rau thaj chaw loj dua, yog li lub siab yuav txo
Thaum twg qhov kev faib yog tus lej chromosome txo qis hauv meiosis?
Thawj qhov kev faib yog hu ua kev txo qis - lossis meiosis I - vim tias nws txo cov chromosomes ntawm 46 chromosomes lossis 2n rau 23 chromosomes lossis n (n piav qhia txog ib qho chromosomes)
Qhov txo qis hauv cellular respiration yog dab tsi?
Lub zuag qhia tag nrho cov tshuaj tiv thaiv ntawm cellular respiration converts ib rau-carbon molecule ntawm qabzib thiab rau molecules ntawm oxygen mus rau hauv rau molecules ntawm carbon dioxide thiab rau molecules dej. Yog li cov pa roj carbon monoxide hauv cov piam thaj ua oxidized, thiab cov pa oxygen txo qis
