Cov ntaub ntawv inhibitor-bound complex feem ntau nyob rau hauv cov ntsiab lus ntawm cov substrate siab thiab ES-I complex tsis tuaj yeem tso cov khoom thaum lub inhibitor yog khi, yog li ua rau txo Vmax. … Yog li, paradoxically, uncompetitive inhibition ob leeg txo Vmax thiab ua rau kom ib tug enzyme affinity rau nws substrate.
Yuav ua li cas tsis sib tw inhibitor cuam tshuam rau Vmax?
Thaum tus tsis sib tw inhibitor ntxiv Vmax hloov, thaum Km tseem tsis hloov. Raws li Lineweaver-Burk zaj duab xis lub Vmax yog txo thaum lub sij hawm ntxiv ntawm ib qho kev sib tw inhibitor, uas yog qhia nyob rau hauv cov zajlus los ntawm ib tug kev hloov nyob rau hauv ob qho tib si txoj kab nqes thiab y-intercept thaum ib tug tsis sib tw inhibitor ntxiv.
Vim li cas Vmax txo qis hauv kev txwv tsis pub sib tw?
Rau qhov sib tw inhibitor, Vmax yog tib yam li rau cov enzyme ib txwm, tab sis Km loj dua. Rau cov noncompetitive inhibitor, Vmax yog qis dua rau cov enzyme ib txwm, tab sis Km yog tib yam. … Cov substrate ntxiv ua rau cov substrate molecules ntau txaus kom tsis tu ncua "sib ntaus" cov inhibitor molecules rau lub enzyme.
Vim li cas Km thiab Vmax yuav txo qis thaum tsis muaj kev sib tw inhibitor ntxiv?
Tsis sib tw inhibitors khi tsuas yog rau cov enzyme-substrate complex, tsis yog rau cov enzyme dawb, thiab lawv txo ob qho tib si kcat thiab Km (qhov txo qis hauv Km stems los ntawm qhov tseeb tias lawv lub xub ntiag rub lub cev tawm mus. los ntawm dawb enzyme mus rau enzyme-substrate complex).
Vmax txo qis txhais li cas?
A qis Vmax txhais tau hais tias lub enzyme ua haujlwm hauv qhov zoo tshaj plaws.

Vim li cas kev tsis sib haum xeeb txo qis km?
Tsis sib tw inhibitors khi tsuas yog rau cov enzyme-substrate complex, tsis yog rau cov enzyme dawb, thiab lawv txo qis kcat thiab Km (qhov txo qis hauv Km stems los ntawm qhov tseeb tias lawv lub xub ntiag rub lub cev tawm mus. los ntawm dawb enzyme mus rau enzyme-substrate complex) .
Qhov txawv ntawm kev txo qis thiab tsis txo cov suab thaj yog dab tsi?
Txo cov suab thaj yog cov suab thaj uas cov pa roj carbon monoxide muaj OH pawg txuas uas tuaj yeem txo lwm cov tebchaw. Tsis yog- txo cov suab thaj tsis muaj OH pawg txuas nrog cov pa roj carbon monoxide kom lawv tsis tuaj yeem txo lwm cov tebchaw… M altose thiab lactose txo cov suab thaj, thaum sucrose yog cov piam thaj tsis txo qis .
Kev kho hauv zej zog puas txo qis vim li cas lossis vim li cas ho tsis?
Kev kho cov neeg koom nrog hauv chaw pw hav zoov tag nrho tsis muaj qhov sib txawv ntawm cov nqi rov ua dua los ntawm pab pawg ntawm cov neeg raug foob thiab raug kaw. Txawm hais tias tej zaum yuav muaj qee qhov kev tshawb fawb qhia qhov sib txawv me me-tshwj xeeb yog cov kev pab cuam nrog cov kev kho mob-cov txiaj ntsig tag nrho tsis txawv ntawm kev txo qis kev ua phem rau yav tom ntej .
Nyob rau hauv ib qho kev tsis sib haum xeeb pn kev sib tshuam cov kev sib tshuam tam sim no ntawm qhov sib npaug yog?
Nyob rau hauv qhov tsis ncaj ncees PN-kho qhov kev sib tshuam tam sim no ntawm qhov sib npaug yog zero, vim tias sib npaug tab sis cov neeg nqa khoom hla hla kev sib tshuam . Thaum pn kev sib tshuam tsis ncaj ncees qhov kev sib tshuam tam sim no ntawm qhov sib npaug yog?
