Kev ua haujlwm enzyme nce li kub nce, thiab nyob rau hauv lem nce tus nqi ntawm cov tshuaj tiv thaiv. Qhov no kuj txhais tau tias kev ua si txo qis thaum txias dua kub . Tag nrho cov enzymes muaj ntau yam ntawm kub thaum lawv ua haujlwm, tab sis muaj tseeb kub qhov twg lawv ua haujlwm zoo.
Ib yam li ntawd, ua haujlwm enzyme cuam tshuam li cas los ntawm qhov kub thiab txias?
Kev kub ntxhov . 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 nce lub kev ua si ntawm feem ntau cov enzymes los ntawm 50 mus rau 100%. Ib txhia cov enzymes poob lawv kev ua si thaum khov.
Qhov thib ob, dab tsi cuam tshuam rau kev ua haujlwm enzyme? 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.
Ib tug kuj yuav nug, yuav ua li cas tshwm sim rau enzymes thaum kub nce?
Nce hauv kub nce kev ua haujlwm molecular, thiab tuaj yeem ua rau muaj kev sib tsoo ntau dua ntawm cov enzymes thiab substrate. Yog tias kub nce siab heev, txawm li cas los xij, lub cov enzymes tuaj yeem ua denatured, thiab cov teebmeem zoo ntawm cov kub nce tuaj yeem yog nullified.
Koj ntsuas kev ua enzyme li cas?
Kev ntsuam xyuas enzyme
- Enzyme assay yog txoj hauv kev los ntsuas kev ua haujlwm enzymatic.
- Qhov kom muaj nuj nqis lossis concentration ntawm ib qho enzyme tuaj yeem qhia tau nyob rau hauv cov nyiaj molar, xws li nrog rau lwm yam tshuaj, lossis hais txog kev ua haujlwm hauv enzyme units.
- Kev ua enzyme = moles ntawm substrate hloov dua siab tshiab rau ib chav tsev lub sij hawm = tus nqi × cov tshuaj tiv thaiv ntim.

Qhov cuam tshuam ntawm qhov kub thiab txias ntawm qhov sib faib coefficient yog dab tsi?
Ib qho inverse linear kev sib raug zoo tau pom ntawm qhov kub thiab txias thiab qhov sib faib coefficient. CEEB TOOM: Nyob rau hauv ib qho kev ntsuas kub, qhov sib faib coefficients isoflurane thiab sevoflurane txo qis thaum qhov kub nce. Sevoflurane qhia tau hais tias muaj kev solubility siab hauv Oxygent (TM) piv rau isoflurane
Lub hnub ncaj qha thiab tsis ncaj qha cuam tshuam li cas rau qhov kub thiab txias?
Lub hnub ncaj qha los tsoo lub ntiaj teb saum npoo ua rau muaj qhov kub thiab txias dua li lub hnub ci ncaj qha. Lub hnub ci dhau los ntawm huab cua tab sis tsis sov nws. Tsis tas li ntawd, lub teeb lub zog los ntawm lub hnub tsoo cov kua thiab cov khib nyiab ntawm lub ntiaj teb. Lub hnub ci poob sib npaug ntawm lawv txhua tus
Qhov nqus thiab tso tawm ntawm lub zog cuam tshuam li cas rau qhov kub thiab txias thaum lub sij hawm muaj tshuaj tiv thaiv?
Nyob rau hauv endothermic cov tshuaj tiv thaiv cov enthalpy ntawm cov khoom yog ntau dua cov enthalpy ntawm cov reactants. Vim tias cov tshuaj tiv thaiv tso tawm lossis nqus lub zog, lawv cuam tshuam rau qhov kub ntawm lawv ib puag ncig. Exothermic cov tshuaj tiv thaiv cua sov ua rau lawv ib puag ncig thaum cov tshuaj tiv thaiv endothermic txias rau lawv
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
