Vim feem ntau cov tshuaj tiv thaiv enzyme yog thim rov qab, ib qho enzyme tuaj yeem tsim thiab decompose molecules. Enzymes cov tshuaj tiv thaiv yog nyob ntawm ntau yam: pH, kub, thiab concentration ntawm ob qho tib si enzyme thiab substrate.
Yuav ua li cas rov qab enzyme yog dab tsi?
Kev ua haujlwm tsis ntev los no tau tsim qhov tseeb tias enzyme kev ua haujlwm kuj muaj peev xwm thim rov qab, yog li thaum muaj xwm txheej zoo, cov khoom ntawm hydrolytic splitting, yog tias qhov no tau hloov pauv, rov koom ua ke los ntawm tib lub enzyme uas cais lawv mus rau hauv thawj, ntau txoj hauv kev molecule.
Vim li cas cov enzymes thim rov qab?
Ib tug thim rov qab enzyme inhibitor yog molecule uas khi reversibly rau cov enzyme thiab qeeb qeeb, lossis inhibits, cov tshuaj tiv thaiv. Nyob rau hauv sib piv rau irreversible inhibition, reversible enzyme inhibition tsis koom nrog covalent hloov.
Yuav ua li cas thim rov qab?
Hauv paus ntsiab lus, tag nrho cov tshuaj tiv thaiv tshuaj yog cov tshuaj tiv thaiv rov qab. Qhov no txhais tau hais tias cov khoom tuaj yeem hloov pauv rov qab mus rau qhov qub reactants.
Piv txwv ntawm cov tshuaj tiv thaiv uas mus ua kom tiav yog:
- ua tiav combustion ntawm roj.
- ntau nag los nag.
- reactions nyob rau hauv uas cov khoom khiav tawm, feem ntau yog ib tug roj.
Puas cov tshuaj tiv thaiv enzymatic rov siv tau?
Enzymes yog reusable . Enzymes tsis reactants thiab tsis siv thaum lub sij hawm.cov tshuaj tiv thaiv. Thaum ib qho enzyme khi rau lub substrate thiab catalyzes cov tshuaj tiv thaiv, cov enzyme raug tso tawm, tsis hloov pauv, thiab tuaj yeem siv rau lwm cov tshuaj tiv thaiv.
