Kev nce cov tshuaj tiv thaiv ntawm cov tshuaj tiv thaiv kab mob tso cai rau cov tshuaj tiv thaiv ntau dua muaj txiaj ntsig , thiab yog li ntau cov khoom yog generated ntawm tus nqi nrawm dua. Qhov no yog lub npe hu ua catalytic efficiency ntawm cov enzymes , uas, los ntawm kev nce tus nqi, ua rau ntau dua muaj txiaj ntsig tshuaj tiv thaiv nyob rau hauv ib tug biological system.

Hauv qhov no, tus nqi kinetic twg txhais tau tias kev ua haujlwm ntawm enzyme?

Specificity constant.), yog ib qho kev ntsuas ntawm qhov ua tau zoo npaum li cas enzyme converts substrates rau hauv cov khoom. Ib qho kev sib piv ntawm qhov tshwj xeeb tsis tu ncua kuj tuaj yeem siv los ntsuas qhov kev nyiam ntawm ib qho enzyme rau txawv substrates (piv txwv li, substrate specification).

Kuj Paub, dab tsi yog qhov cuam tshuam ntawm enzyme concentration ntawm kev ua enzyme? Los ntawm kev nce cov enzyme concentration , qhov siab tshaj plaws cov tshuaj tiv thaiv zoo heev nce. Cov ntsiab lus: Tus nqi ntawm cov tshuaj tiv thaiv kab mob nce raws li cov substrate concentration nce. Enzymes tuaj yeem ceev tus nqi ntawm cov tshuaj tiv thaiv. Txawm li cas los xij, cov enzymes ua saturated thaum lub substrate concentration yog siab.

Tsis tas li ntawd, vim li cas cov duab ntawm ib qho enzyme tseem ceeb?

Cov lub cev ntawm ib qho enzyme yog heev tseem ceeb vim nws muaj kev cuam tshuam ncaj qha rau nws li cas catalyzes cov tshuaj tiv thaiv. Ib enzyme lub cev yog txiav txim los ntawm ib theem ntawm cov amino acids nyob rau hauv nws cov qauv, thiab cov bonds uas tsim ntawm cov atoms ntawm cov molecules.

Dab tsi yog qhov ceev tshaj plaws enzyme?

Carbonic anhydrase
