Kev nce cov tshuaj tiv thaiv ntawm cov tshuaj tiv thaiv kab mob tso cai rau cov tshuaj tiv thaiv ntau dua muaj txiaj ntsig , thiab yog li ntau cov khoom tsim tawm ntawm tus nqi nrawm dua. Qhov no yog lub npe hu ua catalytic efficiency ntawm cov enzymes, uas, los ntawm kev nce tus nqi, ua rau ntau dua muaj txiaj ntsig tshuaj tiv thaiv nyob rau hauv ib tug biological system.
Ib yam li ntawd, catalytic efficiency txhais li cas?
kcat = tus naj npawb ntawm cov substrate molecules / lub sij hawm uas qhov chaw enzymatic tuaj yeem ua. qhov no tseem hu ua tus lej turnover. catalytic efficiency = yuav ua li cas "zoo" ib qho enzyme nyob rau hauv catalyzing cov tshuaj tiv thaiv. zoo li yog tias koj xav sib piv cov nqi ntawm ib qho enzyme ua rau ob lub substrates sib txawv lossis ib yam dab tsi.
Tsis tas li ntawd, vim li cas kcat km yog ib qho txiaj ntsig kev ntsuas ntawm catalytic efficiency? loj k miv yog, qhov zoo dua cov tshuaj tiv thaiv rau cov khoom, thiab qhov loj kM yog. k miv /KM ua rau tus nqi tas li ntawd ntsuas catalytic efficiency . Qhov no ntsuas ntawm efficiency yog pab tau nyob rau hauv kev txiav txim seb tus nqi yog txwv los ntawm kev tsim cov khoom los yog tus nqi ntawm cov substrate nyob rau hauv ib puag ncig.
Xav txog qhov no, dab tsi yog cov units rau catalytic efficiency?
Catalytic Efficiency = Kcat/km Kcat = Unit Time-1 Km = Molarity Yog li ntawd, Catalytic Efficiency yuav yog Chav Sijhawm-1/ molarity Yog li, Yog tias kuv muaj ΜM-1min-1
Tus nqi kinetic twg txhais tau tias kev ua haujlwm ntawm enzyme?
Specification tsis tu ncua. Los ntawm Wikipedia, dawb encyclopedia. Hauv thaj chaw biochemistry, qhov tshwj xeeb tsis tu ncua (tseem hu ua kinetic efficiency los yog.), yog ib qho kev ntsuas ntawm qhov ua tau zoo npaum li cas enzyme converts substrates rau hauv cov khoom.

Txoj Cai Lij Choj thiab Kev Ntsuas Kev Ntsuas Li Cas?
Qhov hnyav thiab ntsuas ntsuas yog ib hom kev cai lij choj uas pom nyob rau hauv ntau qhov chaw txiav txim siab tsim cov qauv kev ntsuas rau qhov hnyav thiab ntsuas. Cov cim tseem ceeb ntawm hom no suav nrog: Ntau Qhov Nyuaj thiab Ntsuas Kev Ua Haujlwm (UK) lossis ntau yam kev cai lij choj ua ntej themin England, Wales thiab Scotland. R.S. xyoo 1985 c
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
Cov ntsuas ntsuas puas yuav tsum tau ntsuas?
Cov lus teb luv luv yog Yes! Qhov ntsuas thiab qhov sib npaug, qhov tseeb tag nrho cov cuab yeej niaj hnub no, yuav tsum tau ntsuas kom ntseeg tau tias lawv ua raws li cov lus qhia tshwj xeeb. Tau hais tias, ntau npaum li cas rau calibrate yog ntau vexing los tsim

Qhov ntsuas ntsuas twg ntsuas qhov loj lossis lub zog ntawm av qeeg raws li seismic nthwv dej?
2. Richter scale- yog qhov ntsuas ntawm qhov av qeeg qhov loj raws li qhov loj ntawm qhov av qeeg qhov seismic nthwv dej thiab kev txav mus los. Lub seismic nthwv dej yog ntsuas los ntawm seismograph
