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.

Dab tsi yog qhov txawv ntawm cov tshuaj tiv thaiv thiab tshuaj tiv thaiv?
Raws li nouns qhov txawv ntawm antitype thiab hom yog hais tias antitype yog ib yam dab tsi uas yog cim los yog sawv cev los ntawm ib homthaum hom yog ib pab pawg raws li cov yam ntxwv sib koom; ib hoob . Antitype txhais li cas? 1a:
Thaum twg yog daim ntawv cog lus tiv thaiv comintern tau kos npe?
Anti-Comintern Pact, kev pom zoo ua ntej ntawm Lub Tebchaws Yelemees thiab Nyiv (Lub Kaum Ib Hlis 25, 1936) thiab tom qab ntawd ntawm Ltalis, Lub Tebchaws Yelemees, thiab Nyij Pooj (Lub Kaum Ib Hlis 6, 1937), ostensibly qhia tawm tsam cov Communist International (Comintern) tab sis, los ntawm kev cuam tshuam, tshwj xeeb tawm tsam Soviet Union .
Cov neeg mob tiv thaiv kab mob yuav tsum tau txais cov tshuaj tiv thaiv?
Vim li cas CDC thiaj pom zoo tias cov neeg uas muaj kev tiv thaiv kab mob tiv thaiv kab mob tau txais koob tshuaj mRNA COVID-19 ntxiv los ntxiv rau 2-dose thawj koob tshuaj tiv thaiv kab mob mRNA COVID-19? Cov neeg uas muaj kev tiv thaiv kab mob los yog cov neeg siv tshuaj tiv thaiv kab mob yog nyob ntawm muaj kev pheej hmoo ntau rau tus kab mob COVID-19 hnyav .
Nyob rau hauv ib qho ntxiv cov tshuaj tiv thaiv rau alkene π daim ntawv cog lus ua lub luag haujlwm ntawm?
Cov ntawv sau cov duab: Ntxiv nrog rau cov tshuaj tiv thaiv alkene, pi daim ntawv cog lus ua lub luag haujlwm ntawm nucleophile electrophile tawm hauv pab pawg tawm hauv pawg Lub cev tshwm sim ntawm kev tawm hauv pab pawg muaj peev xwm yog tus nqi ntawm qhov kev tshwm sim tshwm sim.
Thaum kev loj hlob ntawm daim ntawv cog lus txo lub sijhawm?
Lub sijhawm ntawm daim npav xoom-coupon sib npaug sijhawm rau kev loj hlob. Tuav qhov kev loj hlob tsis tu ncua, daim ntawv cog lus lub sijhawm yog qis dua thaum daim coupon tus nqi siab dua, vim yog qhov cuam tshuam ntawm kev them nqi daim coupon ntau dua.
