Enzymes yog proteins uas yog muaj peev xwm ua kom qis zog rau ntau yam biochemical cov tshuaj tiv thaiv . Enzyme catalysis Ib enzyme catalyzes cov tshuaj tiv thaiv biochemical los ntawm kev khi ib lub substrate ntawm qhov chaw ua haujlwm. Tom qab lub tshuaj tiv thaiv tau mus, cov khoom yog tso tawm thiab enzyme tuaj yeem ua kom muaj zog ntxiv cov tshuaj tiv thaiv.
Ib yam li ntawd, nws raug nug, dab tsi yog lub luag haujlwm ntawm enzyme hauv cov tshuaj tiv thaiv biochemical?
Hauv cov kab mob, cov catalysts hu ua cov enzymes . Qhov tseem ceeb, cov enzymes yog cov tshuaj lom neeg lossis cov organic catalysts. Ib enzyme yog ib qho protein uas ua kom ceev a biochemical cov tshuaj tiv thaiv . Ib enzyme ua hauj lwm los ntawm kev txo tus nqi ntawm activation zog xav tau los pib lub tshuaj tiv thaiv.
Tsis tas li ntawd, dab tsi yog biochemical catalyst? A catalyst yog ib yam dab tsi uas tso cai rau cov tshuaj tiv thaiv tshwm sim ntau dua li qhov yuav tshwm sim hauv nws qhov tsis muaj. Biochemical catalysts feem ntau yog cov protein ntau molecules, npe hu ua enzymes, uas khi lub substrate nyob rau hauv ib tug distorted orientation uas "exposes" ib daim ntawv cog lus yuav tsum tau tawg.
Yog li ntawd, dab tsi yog lub hauv paus tshuaj ntawm enzyme catalysis?
Enzyme catalysis yog qhov nce hauv tus nqi ntawm cov txheej txheem los ntawm cov khoom siv roj ntsha, " enzyme ". Feem ntau cov enzymes yog cov proteins, thiab feem ntau cov txheej txheem zoo li no tshuaj cov tshuaj tiv thaiv. Hauv lub enzyme , feem ntau catalysis tshwm sim ntawm ib qho chaw hauv zos, hu ua qhov chaw nquag.
Yuav ua li cas tshwm sim rau ib tug enzyme tom qab ib tug biochemical cov tshuaj tiv thaiv?
Cov enzyme speeds li tshuaj tiv thaiv los ntawm kev txo qis lub zog ua kom xav tau rau lub tshuaj tiv thaiv pib. Sib piv cov activation zog nrog thiab tsis muaj enzyme . Enzymes feem ntau txo qis kev ua kom lub zog los ntawm kev txo lub zog xav tau rau cov reactants los ua ke thiab teb.

Vim li cas cov tshuaj tiv thaiv kev zom zaub mov hu ua hydrolysis cov tshuaj tiv thaiv?
Thaum lub sij hawm zom mov, piv txwv li, decompositionreactions zom cov zaub mov loj rau hauv cov me me los ntawm kev ntxiv cov dej molecules. Hom tshuaj no hu ua hydrolysis. Raws li dej absorbs heatenergy, qee lub zog yog siv los rhuav tshem hydrogenbonds
Puas yog lub zog tsim cov tshuaj tiv thaiv biochemical uas cov organic molecules pab ob qho tib si electron txais thiab pub dawb?
Txhais kev fermentation. Lub zog tsim cov tshuaj tiv thaiv biochemical uas cov organic molecules ua haujlwm ob qho tib si raws li tus neeg txais hluav taws xob thiab tus neeg pub khoom tshwm sim nyob rau hauv cov xwm txheej anaerobic
Cov tshuaj tiv thaiv zoo li cas thaum cov tshuaj nkag mus rau hauv cov hlab ntsha?

Dab tsi yog tshuaj lom neeg cov tshuaj tiv thaiv thiab cov tshuaj tiv thaiv lub cev?
Qhov sib txawv ntawm cov tshuaj tiv thaiv lub cev thiab cov tshuaj tiv thaiv tshuaj yog muaj pes tsawg leeg. Hauv cov tshuaj tiv thaiv tshuaj, muaj kev hloov pauv ntawm cov tshuaj hauv nqe lus nug; nyob rau hauv ib qho kev hloov ntawm lub cev muaj qhov sib txawv ntawm qhov tsos, tsis hnov tsw, los yog cov duab yooj yim ntawm cov qauv ntawm cov teeb meem yam tsis muaj kev hloov pauv hauv cov ntsiab lus
