Kub Cov teebmeem. Zoo li feem ntau cov tshuaj tiv thaiv, tus nqi ntawm ib qho enzyme -catalyzed cov tshuaj tiv thaiv nce raws li qhov kub yog tsa. Ib kaum degree Centigrade nce nyob rau hauv kub yuav nce qhov kev ua si ntawm feem ntau cov enzymes los ntawm 50 mus rau 100%. Nyob rau tib lub sijhawm, enzymes yuav yuav tsum deactivated txawm nruab nrab kub.
Raws li txoj cai, vim li cas cov enzymes muaj qhov kub thiab txias?
Nyob ntawm zoo kub , lub zog kinetic hauv substrate thiab enzyme molecules yog qhov zoo tagnrho rau kev sib tsoo ntau tshaj plaws. Thaum siab kub cov duab ntawm lub enzyme yog hloov kho kom nws tsis ntxiv rau nws cov substrate tshwj xeeb.
Tsis tas li ntawd, yuav ua li cas tshwm sim rau ib qho enzyme yog tias qhov kub thiab txias sib txawv ntawm cov enzymes zoo tshaj plaws? Enzymes nce kev sib tsoo zoo ntawm cov reactants. Enzymes ua haujlwm ntawm zoo kub thiab pH. Cov enzyme tau txais denatured thiab poob nws cov haujlwm lom neeg yog qhov kub thiab txias sib txawv heev . Siab kub tuaj yeem rhuav tshem cov qauv folded thiab cov duab ntawm lub enzyme.
Tsis tas li ntawd, vim li cas qhov kev ua enzyme txo qis thaum kub siab?
Yam cuam tshuam Kev ua haujlwm enzyme Kub : Nce kub feem ntau speeds li cov tshuaj tiv thaiv, thiab txo qis kub slows down ib qho tshuaj tiv thaiv. Txawm li cas los, heev kub kub tuaj yeem ua rau ib qho enzyme kom poob nws cov duab (denature) thiab tsis ua haujlwm. Cov pH siab heev tuaj yeem ua rau cov enzymes rau denature.
Dab tsi yog qhov zoo tshaj plaws rau cov enzymes?
Qhov no zoo kub feem ntau yog nyob ib ncig ntawm tib neeg lub cev kub (37.5 oC) rau qhov cov enzymes hauv tib neeg lub hlwb. Saum toj no kub tus enzyme cov qauv pib tawg (denature) txij thaum nyob rau hauv qhov kub thiab txias intra- thiab intermolecular bonds yog tawg raws li cov enzyme molecules tau txais ntau lub zog kinetic.

Dab tsi yog qhov sib txawv ntawm cov rog yuav cuam tshuam rau kev sib cuam tshuam ntawm cov dej molecules?
1 Teb. Qhov tseeb, dej muaj tag nrho peb hom kev sib xyaw ua ke, nrog qhov muaj zog tshaj plaws yog hydrogen bonding. Txhua yam muaj London dispersion yuam cov kev sib cuam tshuam tsis muaj zog yog ib ntus dipoles uas tsim los ntawm kev hloov ntawm electrons nyob rau hauv ib lub molecule
Nws txhais li cas thaum kev sib raug zoo ntawm kev sib raug zoo ua kev cuam tshuam?
Kev sib raug zoo ntawm ob tus neeg uas txhua tus neeg nyob ntawm thiab tau txais kev txhawb zog, txawm tias muaj txiaj ntsig lossis kev puas tsuaj, los ntawm lwm tus. ib qho kev sib cuam tshuam lossis kev sib raug zoo ntawm ob tus neeg, pab pawg, thiab lwm yam
Dab tsi yog qhov txawv ntawm kev cuam tshuam kev cuam tshuam thiab kev cuam tshuam cuam tshuam?
Paub qhov txawv ntawm kev cuam tshuam kev tsim kho thiab kev cuam tshuam puas tsuaj. Kev tsim kev cuam tshuam tshwm sim thaum lub crests ntawm ob nthwv dej ntxiv ua ke. Kev cuam tshuam kev puas tsuaj tshwm sim thaum lub crest ntawm ib yoj raug txo los ntawm lub trough ntawm lwm tus
Qhov kev ua enzyme cuam tshuam li cas los ntawm qhov kub thiab txias?
Enzyme kev ua ub no nce thaum kub nce, thiab nyob rau hauv lem nce tus nqi ntawm cov tshuaj tiv thaiv. Qhov no kuj txhais tau tias kev ua haujlwm txo qis ntawm qhov txias dua. Tag nrho cov enzymes muaj qhov kub thiab txias thaum lawv ua haujlwm, tab sis muaj qee qhov kub uas lawv ua haujlwm zoo
Dab tsi yog qee qhov piv txwv ntawm kev cuam tshuam tsis zoo ntawm tib neeg ib puag ncig kev cuam tshuam?
Kev ua liaj ua teb tuaj yeem cuam tshuam tsis zoo rau peb ib puag ncig, suav nrog kev poob ntawm biodiversity, dej paug, kev hloov pauv huab cua, av yaig thiab muaj kuab paug
