- Enzymes ceev cov tshuaj tiv thaiv uas coj qhov chaw hauv cov hlwb. Qhov no muaj nuj nqi yog ncaj qha ntsig txog lawv cov qauv ,s ib enzyme ua tshwj xeeb zoo li catalyze ib qho tshuaj tiv thaiv. Poob ntawm qauv ua rau poob ntawm muaj nuj nqi . - Kub, pH, thiab kev tswj cov molecules tuaj yeem cuam tshuam rau kev ua haujlwm ntawm cov enzymes.
Ua kom pom qhov no, tus qauv ntawm cov enzyme cuam tshuam li cas rau nws txoj haujlwm?
Feem ntau cov enzymes yog cov proteins thiab yog li lawv muaj nuj nqi yog tshwj xeeb rau lawv qauv . Cov enzyme khi nrog rau qhov tsim nyog substrate tsuas yog nyob rau hauv qhov tseeb alignment thiab orientation kom txuas cov molecules. Qhov tshwm sim enzyme -substrate complex enables cov tshuaj tiv thaiv tshwm sim.
Ib tug kuj yuav nug, vim li cas lub enzyme lub cev tseem ceeb rau nws txoj haujlwm? Cov puab ntawm ib enzyme yog heev tseem ceeb vim nws muaj kev cuam tshuam ncaj qha rau nws li cas catalyzes cov tshuaj tiv thaiv. Ib enzyme lub cev yog txiav txim los ntawm ib theem zuj zus ntawm cov amino acids nyob rau hauv nws qauv, thiab cov bonds uas tsim ntawm cov atom ntawm cov molecules.
Raws li txoj cai, lub luag haujlwm ntawm enzyme hauv cov kab mob muaj sia yog dab tsi?
Enzymes yog cov roj ntsha molecules (feem ntau yog cov proteins) uas ua rau kom nce tus nqi ntawm txhua yam tshuaj lom neeg uas tshwm sim hauv cov hlwb. Lawv yog ib qho tseem ceeb rau lub neej thiab ua hauj lwm ntau yam tseem ceeb muaj nuj nqi nyob rau hauv lub cev, xws li pab digestion thiab metabolism.
Cov enzymes ua haujlwm li cas ib kauj ruam?
Plaub kauj ruam ntawm Enzyme Action
- Lub enzyme thiab substrate yog nyob rau hauv tib cheeb tsam. Qee qhov xwm txheej muaj ntau tshaj ib lub substrate molecule uas lub enzyme yuav hloov.
- Lub enzyme grabs mus rau lub substrate ntawm ib qho chaw tshwj xeeb hu ua qhov chaw nquag.
- Cov txheej txheem hu ua catalysis tshwm sim.
- Lub enzyme tso tawm cov khoom.

Cov qauv ntawm cov pa roj carbon zoo li cas rau ntau yam ntawm macromolecules pom hauv cov khoom muaj sia?
Cov pa roj carbon atom muaj cov khoom tshwj xeeb uas tso cai rau nws los tsim cov ntawv cog lus rau ntau li plaub lub atoms sib txawv, ua kom muaj ntau yam khoom zoo tagnrho los ua tus qauv tsim qauv, lossis "ncaj qaum," ntawm macromolecules
Vim li cas thiaj tseem ceeb heev rau cov neeg nyob hauv thaj chaw los kawm txog cov pejxeem ntawm ib lub tebchaws?
Vim cov pej xeem muaj kev cuam tshuam loj heev rau peb lub neej, nws yog ib feem tseem ceeb ntawm thaj chaw.Geographers uas kawm tib neeg cov pej xeem tshwj xeeb tshaj yog nyiam cov qauv uas tshwm sim dhau sijhawm. Lawv kawm cov ntaub ntawv xws li muaj pes tsawg tus neeg nyob hauv ib cheeb tsam, yog vim li cas tib neeg nyob qhov twg lawv ua, thiab cov pej xeem hloov pauv li cas
Vim li cas rhiab heev yog qhov tseem ceeb rau cov khoom muaj sia?
Cov khoom muaj sia nyob muaj kev nkag siab rau lawv ib puag ncig. Kev nkag siab zoo yog qhov tseem ceeb vim tias nws tso cai rau cov khoom muaj sia mus ntes thiab teb rau cov xwm txheej hauv ntiaj teb nyob ib puag ncig lawv
Vim li cas nws tseem ceeb heev uas yuav tsum xav txog ntau yam thaum txiav txim siab cov hauv paus hniav ntawm cov kab zauv polynomial?
Piv txwv li, tus naj npawb ntawm lub sij hawm ib tug muab polynomial sib npaug muaj ib lub hauv paus ntawm ib tug muab point yog lub multiplicity ntawm lub hauv paus. Qhov kev xav ntawm ntau qhov tseem ceeb yog qhov tseem ceeb kom suav tau kom raug yam tsis muaj kev qhia tshwj xeeb (piv txwv li, ob lub hauv paus suav ob zaug). Li no cov lus qhia, ' suav nrog ntau ntau'
Tus qauv qauv yog dab tsi Qhov txawv ntawm tus qauv qauv thiab tus qauv molecular yog dab tsi?
Cov mis mos molecular siv cov cim tshuaj thiab cov ntawv sau npe los qhia cov naj npawb ntawm cov atoms sib txawv hauv cov molecule lossis compound. Ib qho empirical formula muab qhov yooj yim tshaj plaws, tag nrho tus lej piv ntawm atoms hauv ib qho chaw. Cov qauv qauv qhia txog kev sib koom ua ke ntawm cov atoms hauv cov molecule
