Enzymes tsis muaj txiaj ntsig ntawm tag nrho cov thermodynamicntawm cov tshuaj tiv thaiv; lawv tsis muaj kev cuam tshuam rau ^G 0r^H ntawm cov tshuaj tiv thaiv, txawm hais tias lawv txo qis lub zog ntawm lub xeev kev hloov pauv, m yog li txo qis lub zog ua kom muaj zog. Txawm li cas los xij, cov enzymes muaj txiaj ntsig zoo rau lub kinetics ntawm cov tshuaj tiv thaiv.
Puas enzymes cuam tshuam rau kinetics?
Zoo li lwm cov catalysts, enzymes tsis hloov txoj haujlwm ntawm qhov sib npaug ntawm cov khoom siv thiab cov khoom Txawm li cas los xij, tsis zoo li cov tshuaj tsis muaj tshuaj tiv thaiv, cov tshuaj tiv thaiv enzyme-catalysed tso tawm saturation kinetics. … Yog li, KM yog lub substrate concentration uas cov tshuaj tiv thaiv tshaj tawm yog ib nrab ntawm qhov siab tshaj plaws tshaj tawm.
Vim li cas cov enzymes tsis cuam tshuam rau cov thermodynamics?
Enzymes ua haujlwm los ntawm kev txo qis lub zog ua kom muaj zog (Ea lossis ΔG✳) rau cov tshuaj tiv thaiv. Qhov no ua rau cov tshuaj tiv thaiv nce ntxiv. Lub zog pub dawb ntawm cov khoom yog tib yam li nws yuav tsis muaj enzyme. Yog li, cov enzyme tsis cuam tshuam rau lub zog dawb ntawm cov tshuaj tiv thaiv.
Qhov twg ntawm cov tshuaj tiv thaiv ua rau cov enzymes cuam tshuam rau cov thermodynamics ntawm cov tshuaj tiv thaiv lossis cov kinetics ntawm cov tshuaj tiv thaiv?
Enzymes yog cov khoom siv roj ntsha. Catalysts txo qis lub zog ua kom muaj kev cuam tshuam. Qhov qis dua lub zog ua kom muaj zog rau cov tshuaj tiv thaiv, qhov nrawm dua. Yog li enzymes ceev cov tshuaj tiv thaiv los ntawm kev ua kom lub zog qis.
Pob enzymes nce kinetic zog?
Raws li qhov kub thiab txias, cov molecules reacting muaj ntau thiab ntau lub zog kinetic… Saum toj no qhov kub thiab txias cov qauv enzyme pib tawg (denature) txij li thaum kub dua intra- thiab intermolecular. Cov ntawv cog lus tau tawg vim cov enzyme molecules tau txais ntau lub zog kinetic.
