Teb thiab piav qhia: Enzymes tsuas yog ua haujlwm nrog cov substrates tshwj xeeb vim cwb substrate muaj qhov tshwj xeeb 3 qhov loj me.

Yog li ntawd, vim li cas cov enzymes tsuas yog ua haujlwm ntawm qee qhov kev cuam tshuam?

Enzymes yog cov xaiv catalysts heev, txhais tau tias txhua enzyme nkaus xwb speeds ib cov tshuaj tiv thaiv tshwj xeeb . Molecules uas enzyme ua haujlwm nrog hu ua substrates. Cov substrates khi rau ib cheeb tsam ntawm lub enzyme hu ua active site.

Tsis tas li ntawd, dab tsi txiav txim siab qhov tshwj xeeb substrate uas ib qho enzyme tuaj yeem ua rau? Enzymes yog cov protein. Kev ua haujlwm ntawm cov enzyme yog txiav txim siab los ntawm cov qauv ntawm cov protein. Kev kho ntawm molecules ntawm lub enzyme tsim ib cheeb tsam hu ua active site nyob rau hauv uas lub tshwj xeeb substrate (s) yuav "fit". Nws paub, confines thiab orients tus substrate hauv a tshwj xeeb kev taw qhia.

enzymes thiab substrates ua haujlwm ua ke li cas?

Enzymes khi nrog cov tshuaj reactants hu ua substrate . Tej zaum yuav muaj ib lossis ntau dua substrate rau txhua hom enzyme , nyob ntawm cov tshuaj tiv thaiv tshwj xeeb. Hauv qee cov tshuaj tiv thaiv, ib leeg-reactant substrate tau tawg ua ntau yam khoom. Cov cov enzymes active site khi rau lub substrate.

Dab tsi 4 yam tuaj yeem cuam tshuam txoj kev enzymes ua haujlwm?

Ob peb yam cuam tshuam rau tus nqi ntawm cov tshuaj tiv thaiv enzymatic mus - kub , pH, enzyme concentration, substrate concentration, thiab muaj cov inhibitors lossis activators.
