Cov nyhuv ntawm pH

Hloov cov pH ntawm nws ib puag ncig kuj tseem yuav hloov cov duab ntawm qhov chaw nquag ntawm ib qho enzyme . Hloov cov pH yuav cuam tshuam cov nqi ntawm cov amino acid molecules. Amino acids uas nyiam ib leeg yuav tsis muaj lawm. Ntxiv dua thiab, cov duab ntawm lub enzyme , nrog rau nws qhov chaw nquag, yuav hloov.

Kuj tseem paub yog, kev ua haujlwm enzyme cuam tshuam li cas los ntawm pH?

Enzymes yog cuam tshuam los ntawm kev hloov hauv pH . Qhov zoo tshaj plaws pH tus nqi - lub point qhov twg cov enzyme yog qhov nquag tshaj plaws - yog lub npe hu ua qhov zoo tshaj plaws pH . Qhov no yog graphically illustrated nyob rau hauv daim duab 14. Tsis tshua muaj siab los yog qis pH cov txiaj ntsig feem ntau ua rau poob tag kev ua si rau feem ntau cov enzymes.

Tsis tas li ntawd, cov enzymes cuam tshuam li cas los ntawm qhov kub thiab txias? 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 ua kom cov kev ua ntawm feem ntau cov enzymes los ntawm 50 mus rau 100%. Ib txhia cov enzymes poob lawv txoj haujlwm thaum khov.

Yog li, ua li cas rau cov enzymes ntawm pH qis?

Piav: Raws li cov pH txo qis hauv qab qhov zoo tshaj plaws, enzyme kev ua si kuj txo. Thaum kawg pH qis Qhov tseem ceeb, qhov kev cuam tshuam no ua rau cov protein nthuav tawm, cov duab ntawm qhov chaw ua haujlwm yog tsis ntxiv rau lub substrate molecule thiab cov tshuaj tiv thaiv tsis tuaj yeem raug catalysed. enzyme.

Yuav ua li cas pH cuam tshuam rau enzyme quizlet?

Raws li pH nce, kev ua haujlwm enzyme nce mus txog thaum nws mus txog qhov zoo tshaj plaws uas cov enzymes denatures thiab as pH nce, kev ua haujlwm enzyme txo. Lawv kuj tuaj yeem cuam tshuam nrog qhov chaw nquag thiab cuam tshuam hydrogen khi thiab khi rau ionic residues txo qis, lossis qee zaum nce ntxiv, kev ua si ntawm enzyme.
