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.

Lub kaum sab xis ntawm qhov cuam tshuam cuam tshuam li cas rau cov tsos ntawm cov ntshav?
Thaum cov ntshav raug cuam tshuam, cov tee dej tau tawg los ntawm huab cua. Thaum cov tee dej no tawm tsam ib qho chaw, cov duab ntawm cov stain hloov nyob ntawm lub kaum sab xis ntawm qhov cuam tshuam, kev tshaj tawm, kev ncua deb thiab hom ntog cuam tshuam. Raws li lub kaum sab xis ntawm qhov cuam tshuam hloov, yog li qhov tshwm sim ntawm qhov tshwm sim stain
Yuav ua li cas cov tsev neeg ntawm kev ua haujlwm tsis thiab cov lus piav qhia ntawm cov duab cuam tshuam?
Cov tsev neeg muaj nuj nqi yog pab pawg ua haujlwm nrog qhov zoo sib xws uas ua rau lawv yooj yim rau kev teeb tsa thaum koj paub txog kev ua haujlwm ntawm niam txiv, qhov piv txwv yooj yim tshaj plaws ntawm daim ntawv. Ib qho parameter yog qhov sib txawv hauv cov kab zauv dav dav uas siv rau ntawm tus nqi tshwj xeeb txhawm rau tsim ib qho kev sib npaug
Dab tsi yog qhov sib txawv ntawm cov rog yuav cuam tshuam rau kev sib cuam tshuam ntawm cov dej molecules?
1 Teb. Qhov tseeb, dej muaj tag nrho peb hom kev sib xyaw ua ke, nrog qhov muaj zog tshaj plaws yog hydrogen bonding. Txhua yam muaj London dispersion yuam cov kev sib cuam tshuam tsis muaj zog yog ib ntus dipoles uas tsim los ntawm kev hloov ntawm electrons nyob rau hauv ib lub molecule
Dab tsi yog qhov txawv ntawm kev cuam tshuam kev cuam tshuam thiab kev cuam tshuam cuam tshuam?
Paub qhov txawv ntawm kev cuam tshuam kev tsim kho thiab kev cuam tshuam puas tsuaj. Kev tsim kev cuam tshuam tshwm sim thaum lub crests ntawm ob nthwv dej ntxiv ua ke. Kev cuam tshuam kev puas tsuaj tshwm sim thaum lub crest ntawm ib yoj raug txo los ntawm lub trough ntawm lwm tus
Dab tsi yog qee qhov piv txwv ntawm kev cuam tshuam tsis zoo ntawm tib neeg ib puag ncig kev cuam tshuam?
Kev ua liaj ua teb tuaj yeem cuam tshuam tsis zoo rau peb ib puag ncig, suav nrog kev poob ntawm biodiversity, dej paug, kev hloov pauv huab cua, av yaig thiab muaj kuab paug
