Thaum lub sijhawm muaj cov tshuaj tiv thaiv catalytic cov hauv qab no tshwm sim: 1) Substrate yog covalently khi thiab taw qhia nrog qhov sib thooj rau qhov chaw seem seem. 2) Tus nqi tsis zoo ua rau ntawm lub substrate thiab ruaj khov. 3) Oxidation ntawm enzyme ua raws li kev txo qis kom ua tiav lub voj voog catalytic.
Yuav ua li cas tshwm sim hauv cov tshuaj tiv thaiv catalyzed?
Txhawm rau ua kom cov tshuaj tiv thaiv, ib qho enzyme yuav lob rau (khi) rau ib lossis ntau dua reactant molecules. … Qhov no tsim cov enzyme-substrate complex. Cov tshuaj tiv thaiv ces tshwm sim, hloov lub substrate rau hauv cov khoom thiab tsim cov khoom enzyme complex. Cov khoom tom qab ntawd tawm ntawm qhov chaw nquag ntawm cov enzyme.
Yuav ua li cas hauv chav kawm ntawm cov tshuaj tiv thaiv enzyme catalysed?
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.
Cov tshuaj tiv thaiv enzyme catalytic yog dab tsi?
Enzyme catalysis yog nce tus nqi ntawm cov txheej txheem los ntawm cov khoom siv roj ntsha, "enzyme". Feem ntau cov enzymes yog cov proteins, thiab feem ntau cov txheej txheem no yog tshuaj lom neeg. … Enzymes feem ntau yog qhov tshwj xeeb thiab ua rau qee qhov substrates.
Yuav ua li cas thaum muaj cov tshuaj tiv thaiv enzyme catalyzed nyob rau hauv equilibrium?
Hauv luv luv, enzymes tsis hloov lub xeev sib npaug ntawm cov tshuaj tiv thaiv biochemical. ΔG0 thiab Keq tseem zoo li qub. Hloov chaw, lub enzyme txo qis lub zog ua kom xav tau rau cov tshuaj tiv thaiv mus, thiab yog li nce tus nqi ntawm cov tshuaj tiv thaiv.
