Thawj qhov kev txiav txim kinetics tshwm sim thaum ib qho kev faib ua feem ntawm cov tshuaj raug tshem tawm ib lub sijhawm. Tus nqi ntawm kev tshem tawm yog proportional rau tus nqi ntawm cov tshuaj nyob rau hauv lub cev. Qhov siab dua qhov concentration, qhov ntau dua cov tshuaj tshem tawm ib lub sijhawm.

Hauv qhov no, kev tshem tawm thawj zaug yog dab tsi?

Txhais Thawj qhov kev txiav txim tshem tawm kinetics: " Kev tshem tawm ntawm ib feem tsis tu ncua ib lub sij hawm chav tsev ntawm cov tshuaj kom muaj nuj nqis nyob rau hauv lub cev. Cov tshem tawm yog proportional rau cov tshuaj concentration."

Ib yam li ntawd, qhov txawv ntawm thawj qhov kev txiav txim thiab xoom xaj kinetics yog dab tsi? Qhov tseem ceeb qhov sib txawv ntawm xoom thiab ua ntej - xaj kinetics yog lawv tshem tawm tus nqi piv rau tag nrho cov ntshav plasma concentration. Zero - xaj kinetics Kev tshem tawm tas li tsis hais txog ntawm cov ntshav plasma concentration, tom qab ib theem tshem tawm raws li qhov system ua kom txaus.

Ntawm no, dab tsi yog thawj qhov kev txiav txim kinetics ntawm cov tshuaj?

" Ua ntej - xaj kinetics yog qhov uas ib feem tsis tu ncua ntawm tshuaj Nyob rau hauv lub cev raug tshem tawm ib chav tsev ntawm lub sij hawm "Qhov no yog ib tug logarithmic muaj nuj nqi, tag nrho cov enzymes thiab clearance mechanisms ua hauj lwm nyob rau hauv zoo qis dua lawv lub peev xwm siab tshaj plaws, thiab tus nqi ntawm cov enzymes. tshuaj tshem tawm yog ncaj qha proportional rau tshuaj concentration.

Yuav ua li cas koj pom thawj kev txiav txim kinetics?

Integrated Form ntawm a Ua ntej - Order Kinetics Equation Tshwj xeeb, thaum t = 0, [A] = [A]o. [A]o yog tus thawj pib concentration ntawm A. Hloov mus rau hauv lub kev sib npaug , peb tau txais: ln [A]o = - k (0) + C. Nco ntsoov exp notation txhais tau hais tias lub ntuj tas li e tsa rau lub hwj chim ntawm txhua yam raws li nram no.
