Enzymes yog cov roj ntsha molecules (feem ntau yog cov proteins) uas ua rau kom nce tus nqi ntawm tag nrho cov tshuaj. cov tshuaj tiv thaiv uas tshwm sim hauv cov cell. 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.
Hais txog qhov no, dab tsi yog enzymes faib lawv thiab piav qhia lawv lub luag haujlwm?
Cov enzymes yog cov tshuaj lom neeg lom neeg Enzymes yog cov catalysts koom nrog hauv kev lom neeg tshuaj tiv thaiv . Lawv yog cov "gnomes" hauv peb txhua tus uas coj cov molecules zoo li nucleotides thiab ua kom lawv ua ke los tsim DNA, lossis amino acids los ua. cov proteins , mus rau npe ob ntawm txhiab ntawm cov haujlwm no.
Tom qab ntawd, lo lus nug yog, dab tsi yog siv cov enzymes? Enzymes yog siv nyob rau hauv cov zaub mov, kev ua liaj ua teb, tshuaj pleev ib ce, thiab tshuaj industries los tswj thiab ceev cov tshuaj tiv thaiv nyob rau hauv thiaj li yuav sai thiab meej kom tau ib tug tseem ceeb kawg cov khoom. Enzymes Nws yog ib qho tseem ceeb rau kev ua cheese, brewing npias, ci qhob cij, rho cov kua txiv hmab txiv ntoo, tanning tawv, thiab lwm yam.
Qhov thib ob, hom tshuaj enzyme twg muaj?
Hom Enzymes
- Oxidoreductases txhim kho tus nqi ntawm oxidation thiab txo cov tshuaj tiv thaiv.
- Transferases ceev raws li kev hloov ntawm pawg ntawm atoms, xws li methyl (CH3), acetyl (CH3CO) los yog amino (NH2) pawg, los ntawm ib lub molecule mus rau lwm lub molecule.
- Hydrolases ceev cov tshuaj tiv thaiv hydrolysis.
Cov enzymes tsim nyob qhov twg?
Enzymes yog tsim nyob rau hauv lub cev. Piv txwv li, enzymes yuav tsum tau ua kom zoo digestive system. Digestive enzymes feem ntau yog tsim nyob rau hauv lub pancreas , plab, thiab hnyuv.

Lub luag haujlwm ntawm CDK yog dab tsi hauv lub cev ua haujlwm ntawm tes tshwj xeeb hauv lub voj voog ntawm tes?
Los ntawm phosphorylation, Cdks teeb liab lub xov tooj ntawm tes uas nws tau npaj kom dhau mus rau theem tom ntej ntawm lub voj voog ntawm tes. Raws li lawv lub npe qhia, Cyclin-Dependent Protein Kinases yog nyob ntawm cyclins, lwm chav kawm ntawm kev tswj hwm cov protein. Cyclins khi rau Cdks, ua kom cov Cdks rau phosphorylate lwm cov molecules
Vim li cas cov tshuaj tiv thaiv kev zom zaub mov hu ua hydrolysis cov tshuaj tiv thaiv?
Thaum lub sij hawm zom mov, piv txwv li, decompositionreactions zom cov zaub mov loj rau hauv cov me me los ntawm kev ntxiv cov dej molecules. Hom tshuaj no hu ua hydrolysis. Raws li dej absorbs heatenergy, qee lub zog yog siv los rhuav tshem hydrogenbonds
Lub npe rau ib yam khoom tsim nyob rau hauv cov tshuaj tiv thaiv tshuaj yog dab tsi?
Cov tshuaj tiv thaiv tshuaj yog cov txheej txheem uas cov atoms tam sim no nyob rau hauv cov tshuaj pib rov ua kom muab cov tshuaj sib xyaw tshiab tam sim no hauv cov tshuaj tsim los ntawm cov tshuaj tiv thaiv. Cov tshuaj pib ntawm cov tshuaj tiv thaiv tshuaj hu ua reactants, thiab cov tshuaj tshiab uas tshwm sim hu ua cov khoom
Cov tshuaj tiv thaiv dab tsi yog qhov tshuaj tiv thaiv neutralization?
Neutralization yog ib hom tshuaj tiv thaiv nyob rau hauv uas muaj zog acid thiab muaj zog puag react nrog ib leeg los tsim dej thiab ntsev
Dab tsi yog tshuaj lom neeg cov tshuaj tiv thaiv thiab cov tshuaj tiv thaiv lub cev?
Qhov sib txawv ntawm cov tshuaj tiv thaiv lub cev thiab cov tshuaj tiv thaiv tshuaj yog muaj pes tsawg leeg. Hauv cov tshuaj tiv thaiv tshuaj, muaj kev hloov pauv ntawm cov tshuaj hauv nqe lus nug; nyob rau hauv ib qho kev hloov ntawm lub cev muaj qhov sib txawv ntawm qhov tsos, tsis hnov tsw, los yog cov duab yooj yim ntawm cov qauv ntawm cov teeb meem yam tsis muaj kev hloov pauv hauv cov ntsiab lus
