Enzyme catalysis kuaj pom los ntawm kev ntsuas qhov pom ntawm cov khoom lossis ploj ntawm cov reactants. Rau ntsuas ib yam, koj yuav tsum muaj peev xwm pom nws. Enzyme kev ntsuam xyuas yog cov kev xeem tsim los rau ntsuas kev ua haujlwm enzyme los ntawm kev ntsuas qhov kev hloov pauv hauv qhov concentration ntawm cov khoom uas kuaj tau.

Tib neeg kuj nug, qhov twg hauv qab no tuaj yeem cuam tshuam tus nqi ntawm cov tshuaj tiv thaiv enzyme catalyzed?

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

Qhov thib ob, qhov piv txwv ntawm cov tshuaj tiv thaiv enzyme catalyzed yog dab tsi? Cov cov tshuaj tiv thaiv yog: Oxidation thiab txo. Enzymes uas ua cov no cov tshuaj tiv thaiv hu ua oxidoreductases. Rau piv txwv , cawv dehydrogenase hloov cov cawv thawj rau aldehydes.

Dhau li ntawm qhov no, dab tsi yog enzyme catalysed cov tshuaj tiv thaiv?

Enzyme catalysed cov tshuaj tiv thaiv tshwm sim ntawm ib qho chaw tshwj xeeb ntawm qhov chaw loj enzyme molecule hu ua active site (raws li nyob rau hauv heterogeneous catalysts). Lub reactant molecule, feem ntau hu ua lub substrate, muaj peev xwm tsim tau kuj tsis muaj zog, ib ntus daim ntawv cog lus rau lub enzyme ntawm qhov chaw nquag.

Koj ntsuas kev ua enzyme li cas?

Kev ua haujlwm enzyme = moles ntawm substrate hloov dua siab tshiab rau ib chav tsev lub sij hawm = tus nqi × cov tshuaj tiv thaiv ntim. Kev ua haujlwm enzyme yog a ntsuas ntawm qhov ntau ntawm active enzyme tam sim no thiab yog li nyob ntawm tej yam kev mob, uas yuav tsum tau teev.
