Enzymes yog cov khoom siv roj ntsha. Catalysts txo qis lub zog ua kom muaj kev cuam tshuam. Qhov qis dua lub zog ua kom muaj zog rau cov tshuaj tiv thaiv, qhov nrawm dua. Yog li enzymes ceev cov tshuaj tiv thaiv los ntawm kev ua kom lub zog qis.
Thaum twg ib qho enzyme catalyzes cov tshuaj tiv thaiv nws yog siv ib zaug thiab muab pov tseg?
In Summary: Enzymes
Enzymes yog cov proteins uas ua kom muaj kev cuam tshuam los ntawm kev txo qis kev ua kom lub zog. Txhua lub enzyme feem ntau khi tsuas yog ib qho substrate. Enzymes tsis noj thaum lub sijhawm tshuaj tiv thaiv; es tsis txhob lawv muaj los khi cov substrates tshiab thiab catalyze tib cov tshuaj tiv thaiv ib zaug.
Puas yog ib qho enzyme catalyze ib qho tshuaj tiv thaiv?
Ib qho enzyme feem ntau catalyzes ib qho tshuaj tiv thaiv ib leeg lossis ib pawg ntawm cov tshuaj tiv thaiv zoo sib xws. Cov tshuaj tiv thaiv sab uas ua rau cov khoom pov tseg ntawm cov khoom lag luam tsis tshua muaj nyob rau hauv cov tshuaj tiv thaiv enzyme-catalyzed, sib piv nrog cov tsis muaj tshuaj lom.
Qhov tshwm sim ntawm cov tshuaj tiv thaiv enzymatic yog dab tsi?
Ib enzyme nyiam substrates rau nws qhov chaw nquag, catalyzes cov tshuaj tiv thaiv los ntawm cov khoom tsim, thiab tom qab ntawd tso cai rau cov khoom sib cais (sib cais los ntawm enzyme nto). Kev sib xyaw ua ke tsim los ntawm ib qho enzyme thiab nws cov substrates yog hu ua enzyme-substrate complex.
4 kauj ruam ntawm kev ua enzyme yog dab tsi?
Plaub kauj ruam ntawm Enzyme Action
- Lub enzyme thiab lub substrate nyob rau tib cheeb tsam. Qee qhov xwm txheej muaj ntau tshaj ib lub substrate moleculeuas lub enzyme yuav hloov.
- Lub enzyme rub mus rau lub substrate ntawm ib qho chaw tshwj xeeb hu ua qhov chaw nquag. …
- Ib txheej txheem hu ua catalysis tshwm sim. …
- Cov enzyme tso tawm cov khoom.
