Ib feem ntawm cov enzyme uas khi lub substrate los ua rau yog hu ua qhov chaw nquag. Thaum lub substrate raug kaw rau hauv lub enzyme, ob daim ntsuab substrate tej zaum yuav yooj yim rub tawm. Hom txheej txheem metabolic no hu ua catabolism (kev rhuav tshem ntawm cov molecules complex rau hauv cov molecules yooj yim dua).
YPuas enzyme khi rau substrate lossis puas substrate khi rau enzyme?
Enzymes yog cov proteins uas muaj peev xwmkhi substratehauv lawv qhov chaw nquag thiab tom qab ntawd hloov kho cov txheej txheem khi, hloov mus rau qhov sib txawv - cov khoom ntawm cov tshuaj tiv thaiv. Substrates khi rau enzymes ib yam li ligands khi rau cov proteins.
Yuav ua li cas cov enzyme thiab substrate haum ua ke?
Rau ib qho enzyme thiab substrate rau khi lawv yuav tsum haum ua ke lub cev. Txhua lub enzyme muaj ib cheeb tsam ntawm nws qhov chaw hu ua qhov chaw nquag (Daim duab 3). Qhov no yog cleft nyob rau hauv cov protein nto qhov twg lub substrate khi. Nws muaj cov duab uas haum rau lub substrate zoo li hnab looj tes haum rau tes lossis lub xauv haum rau tus yuam sij.
Thaum hais txog enzymes lub substrate khi rau dab tsi?
Enzymes yog tshwj xeeb rau substrates raws li lawv muaj ib qhov chaw nquaguas tsuas yog tso cai rau qee qhov substrates los khi rau lub xaib nquag. Qhov no yog vim cov duab ntawm lub vev xaib nquag thiab lwm yam substrates tsis tuaj yeem khi rau qhov chaw nquag. muaj ib tug qauv uas yog paub zoo nyob rau hauv lubbiology teb ntawm lub xauv thiab tus qauv tseem ceeb.
Yuav ua li cas tom qab ib qho enzyme khi rau lub substrate?
Thaum ib qho enzyme khi nws cov substrate, nws tsim cov enzyme-substrate complex. … Ib qho ntawm cov khoom tseem ceeb ntawm cov enzymes yog tias lawv nyob twj ywm thaum kawg tsis hloov pauv los ntawm cov tshuaj tiv thaiv lawv catalyze. Tom qab ib qho enzyme ua tiav catalyzing cov tshuaj tiv thaiv, nws tso nws cov khoom (substrates).
