V_max qhia nrawm npaum li cas cov enzyme tuaj yeem ua rau cov tshuaj tiv thaiv … Ib qho enzyme K_mpiav qhia txog lub substrate concentration uas ib nrab ntawm cov enzymes active sites yog nyob los ntawm substrate. Lub siab K_{m txhais tau tias ntau lub substrate yuav tsum muaj tam sim no kom saturate lub enzyme, txhais tau tias cov enzyme tsis muaj affinity rau lub substrate.}

Vmax yog dab tsi hauv enzyme kinetics?

Vmax yog cov tshuaj tiv thaiv tus nqi thaum lub enzyme yog tag nrho saturated los ntawm substrate, qhia tias tag nrho cov binding qhov chaw tau tas li reoccupied.

Vmax yog dab tsi thiab nws qhov tseem ceeb?

Nyob rau hauv enzyme kinetics, V_max yog qhov siab tshaj plaws los yog tus nqi uas cov enzyme catalyzed ib qho tshuaj tiv thaiv Nws tshwm sim thaum tag nrho cov enzyme active chaw yog saturated nrog substrate. Txij li qhov siab tshaj plaws tshaj tawm tau piav qhia ncaj qha ncaj qha rau enzyme concentration, nws tuaj yeem siv los kwv yees enzyme concentration.

Dab tsi cuam tshuam rau Vmax ntawm ib qho enzyme?

Txawm hais tias cov enzymes yog cov catalysts, Vmax ua nyob ntawm cov enzyme concentration, vim nws tsuas yog tus nqi xwb, mol / sec - ntau enzyme yuav hloov ntau cov substrate moles rau hauv cov khoom. Nyob rau hauv tus qauv Michealis-Menten kinetics cov tshuaj tiv thaiv tas li yog proportional rau tus nqi ntawm decomposition ntawm ES (enzyme-substrate complexes).

KM thiab Vmax yog dab tsi?

Vmax yog qhov siab tshaj plaws ntawm cov tshuaj tiv thaiv enzyme catalysed xws li thaum cov enzyme saturated los ntawm substrate. Km yog ntsuas qhov yooj yim npaum li cas cov enzyme tuaj yeem saturated los ntawm substrateKm thiab Vmax yog tas li rau qhov muab kub thiab pH thiab siv los ua tus yam ntxwv ntawm cov enzymes.
