Enzymes ua kom cov tshuaj tiv thaiv los ntawm kev nqa cov reactants ua ke thiab txo cov kev ua kom lub zog yuav tsum tau pib muaj ( enzymatic tshuaj tiv thaiv). Enzymes yog qhov tshwj xeeb: lawv muaj cov duab tshwj xeeb, yog li tsuas yog qee qhov substrate yuav haum nws qhov chaw nquag.

Tom qab ntawd, ib tug kuj yuav nug, dab tsi yog cov yam ntxwv ntawm enzyme catalysis?

Cov yam ntxwv ntawm enzyme catalysis (1) Lawv ua haujlwm zoo heev. Ib molecule ntawm ib enzyme tuaj yeem hloov cov molecules ntawm reactants ib feeb. (2) Lawv yog cov tshwj xeeb hauv cov xwm txheej e.r., urease catalyseshydrolysis ntawm urea nkaus xwb. (3) Lawv ua haujlwm ntawm qhov kub thiab txias.

Kuj Paub, dab tsi yog ib qho enzyme thiab nws txoj haujlwm yog dab tsi? Enzymes yog cov roj ntsha molecules (feem ntau yog cov protein) uas ua kom nrawm nrawm ntawm txhua yam tshuaj lom neeg uas tshwm sim hauv cov hlwb. Lawv yog cov tseem ceeb rau lub neej thiab pab ntau yam tseem ceeb muaj nuj nqi nyob rau hauv lub cev, xws li pab digestion thiab metabolism.

Ntawm no, 3 lub luag haujlwm ntawm enzymes yog dab tsi?

Hauv lwm lo lus, ib enzyme yog protein-based catalyst. Enzymes catalyze txhua yam tshuaj tiv thaiv uas koom nrog hauv kev loj hlob, ntshav coagulation, kho, kab mob, ua pa, plab zom mov, kev loj hlob, thiab ntau lwm yam kev ua haujlwm lom neeg.

Dab tsi yog 5 enzymes?

Qee qhov enzymes muaj xws li:

  • Erepsin: hloov peptones thiab polypeptides rau hauv aminoacids.
  • Maltase: hloov maltose rau hauv qabzib.
  • Lactase: Qhov no yog ib qho tseem ceeb enzyme uas hloov lactosein rau qabzib thiab galactose.
  • Sucrase: hloov sucrose rau hauv qabzib thiab fructose.
  • Lwm yam disaccharidases.
