Thaum ib qho enzyme khi nws cov substrate, nws tsim ib qho enzyme-substrate complex Cov complex no txo qis lub zog ua kom muaj zog ntawm cov tshuaj tiv thaiv thiab txhawb nws txoj kev loj hlob sai los ntawm kev muab qee yam ions lossis tshuaj lom neeg. uas ua tau tsim covalent bonds nrog molecules raws li ib tug tsim nyog kauj ruam ntawm cov tshuaj tiv thaiv txheej txheem.
Yuav ua li cas daim ntawv cog lus cuam tshuam rau substrate khi?
Lub substrate khi rau cov enzyme feem ntau los ntawm hydrogen bonding thiab lwm yam kev cuam tshuam electrostatic. Tus qauv induced-fit hais tias ib qho enzyme tuaj yeem hloov pauv hloov pauv thaum khi lub substrate.
daim ntawv cog lus substrate nyob qhov twg?
Ib feem ntawm cov enzyme uas lub substrate khi yog hu ua qhov chaw nquag(vim qhov ntawd yog qhov chaw catalytic "ua haujlwm" tshwm sim). Ib tug substrate nkag mus rau lub active site ntawm lub enzyme. Qhov no tsim cov enzyme-substrate complex.
Dab tsi yog substrate bonding?
Substrate bonding yog hais txog rau txuas ob lossis ntau lub substrates ntawm cov khoom xws li iav los yog silicon, rau ib leeg los ntawm ntau yam tshuaj thiab lub cev.
Dab tsi yog qhov substrate hauv qhov tshuaj tiv thaiv no?
substrate: Ib qho reactant nyob rau hauv cov tshuaj tiv thaiv yog hu ua substrate thaum ua raws li los ntawm ib tug enzyme induced haum: Tshaj tawm tias thawj zaug kev sib cuam tshuam ntawm enzyme thiab substrate kuj tsis muaj zog, tab sis tias cov kev sib cuam tshuam tsis muaj zog sai ua rau muaj kev hloov pauv hauv cov enzyme uas ntxiv dag zog rau kev khi.
