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.
