Enzymes yog cov protein ua haujlwm li catalysts uas ua kom cov tshuaj tiv thaiv los ntawm kev txo qis lub zog ua kom muaj zog. Ib qho yooj yim thiab succinct txhais ntawm ib enzyme yog tias nws yog biological catalyst uas ua rau kom muaj tshuaj lom neeg tsis muaj kev hloov pauv nws qhov sib npaug.
Hauv qhov no, ua li cas cov enzymes ua haujlwm li molecular catalysts?
Ib yam khoom uas pab tau tshuaj lom neeg rau tshwm sim yog hu ua a catalyst , thiab cov molecules uas catalyze biochemical cov tshuaj tiv thaiv yog hu ua cov enzymes . Enzymes ua qhov no los ntawm kev khi rau tus reactant molecules thiab tuav lawv hauv txoj kev zoo li ua cov chemical bond-breaking thiab-forming txheej txheem coj qhov chaw yooj yim dua.
Ib yam li ntawd, enzymes ua haujlwm li cas? Enzymes yog cov roj ntsha molecules (feem ntau yog cov proteins) uas ua rau kom nce tus nqi ntawm txhua yam tshuaj lom neeg uas tshwm sim hauv cov hlwb. Enzymes yog cov xaiv catalysts heev, txhais tau tias txhua enzyme tsuas yog ua kom cov tshuaj tiv thaiv tshwj xeeb.
Ib yam li ntawd, enzymes catalyze li cas?
Enzymes yog biological catalysts. 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 cov enzymes ua kom cov tshuaj tiv thaiv los ntawm kev txo qis zog ua kom muaj zog.
Vim li cas qhov kev ua haujlwm catalytic ntawm enzymes tseem ceeb?
Cov Catalytic Activity ntawm Enzymes Ua ntej, lawv nce tus nqi ntawm cov tshuaj tiv thaiv tsis muaj lawv tus kheej raug noj lossis hloov pauv mus tas li los ntawm cov tshuaj tiv thaiv. Qhov thib ob, lawv nce cov tshuaj tiv thaiv tsis tau hloov cov tshuaj sib npaug ntawm cov tshuaj reactants thiab cov khoom.

Cov catalysts hauv cov catalytic converters ua tiav li cas?
Catalytic converter substrates Catalytic converters yog siv los txo cov nqi ntawm nitrogen oxides, carbon monoxide, thiab unreacted hydrocarbons nyob rau hauv tsheb emissions. Nyob rau hauv ntau tshaj peb-txoj kev converters ib tus neeg catalysts ua kom txo tau ntawm txhua hom ib txhij
Dab tsi yog enzymes lub luag haujlwm hauv cov tshuaj tiv thaiv?
Enzymes yog cov roj ntsha molecules (feem ntau yog cov proteins) uas ua rau kom nce tus nqi ntawm txhua yam tshuaj lom neeg uas tshwm sim hauv cov hlwb. Lawv yog ib qho tseem ceeb rau lub neej thiab pab ntau yam haujlwm tseem ceeb hauv lub cev, xws li pab digestion thiab metabolism
Yuav ua li cas enzymes ua raws li catalysts?
Enzymes yog cov proteins ua haujlwm ua cov catalysts uas ua rau muaj kev cuam tshuam los ntawm kev txo qis lub zog ua kom muaj zog. Ib qho yooj yim thiab succinct txhais ntawm ib tug enzyme yog tias nws yog ib tug lom catalyst uas accelerates ib tug tshuaj tiv thaiv yam tsis tau hloov nws equilibrium. Nyob rau hauv tag nrho cov txheej txheem, enzymes tsis dhau ib qho kev hloov pauv
Vim li cas enzymes tsuas yog ua haujlwm nrog cov substrates tshwj xeeb?
Teb thiab piav qhia: Enzymes tsuas yog ua haujlwm nrog cov substrates tshwj xeeb vim tias txhua lub substrate muaj qhov tshwj xeeb 3 seem
Cov txheej txheem dab tsi yog lub luag haujlwm rau txoj haujlwm ua haujlwm sib txawv?
Position-effect variegation (PEV) tshwm sim thaum cov noob ib txwm nyob hauv euchromatin yog sib xyaw nrog heterochromatin los ntawm kev hloov kho lossis hloov pauv. Thaum lub ntim ntim heterochromatin kis thoob plaws heterochromatin / euchromatin ciam teb, nws ua rau kev hloov pauv ntawm kev ntsiag to hauv tus qauv stochastic
