Hauv xoom - xaj kinetics , cov tus nqi ntawm ib qho tshuaj tiv thaiv tsis yog nyob ntawm seb lub substrate concentration. Qhov t 1 /2 formula rau xoom xaj tshuaj tiv thaiv qhia cov ib nrab - lub neej nyob ntawm tus nqi ntawm thawj zaug concentration thiab tus nqi tas li.
Tom qab ntawd, ib tug kuj yuav nug, dab tsi yog ib nrab ntawm lub neej rau qhov kev txiav txim xoom?
96 nqi
Tsis tas li ntawd, koj ua li cas thiaj nrhiav tau ib nrab lub neej ntawm tus nqi tas li? Tswv yim:
- Siv Equation 3 los xam qhov ib nrab-lub neej ntawm cov tshuaj tiv thaiv.
- Muab cov concentration thawj zaug los ntawm 1/2 mus rau lub hwj chim sib raug rau tus naj npawb ntawm ib nrab-lub neej kom tau txais qhov seem ntxiv tom qab cov ib nrab-lub neej.
- Tshem tawm qhov seem concentration ntawm qhov pib concentration.
Hais txog qhov no, vim li cas ib nrab ntawm lub neej ntawm thawj qhov kev txiav txim tshwm sim tas li?
Hauv lwm lo lus, qhov pib concentration ntawm cov reactant tsis muaj kev cuam tshuam rau cov ib nrab - lub neej ntawm tshuaj tiv thaiv , i.e. ua ib nrab - lub neej yog tas li tsis hais qhov concentration ntawm cov reactant.
Puas yog ib nrab lub neej ntawm xoom xaj tshuaj tiv thaiv nyob ntawm qhov pib concentration ntawm cov reactant?
Li no, los ntawm qhov sib npaug saum toj no peb ua tau xaus tias cov ib nrab lub neej ntawm qhov kev txiav txim xoom cov tshuaj tiv thaiv nyob ntawm ntawm thawj concentration ntawm reacting hom thiab tus nqi tas li, k. Nws yog ncaj qha proportional rau thawj concentration ntawm cov reactant whereas nws yog inversely proportional rau tus nqi tas li, k.

Yuav ua li cas ntxiv tus inhibitor cuam tshuam tus nqi ntawm cov tshuaj tiv thaiv?
Kev piav qhia: Los ntawm txhais, inhibitors qeeb cov tshuaj tiv thaiv. Yog li ntawd, yog tias koj yuav tsum ntxiv ib qho inhibitor rau cov tshuaj tiv thaiv, koj yuav ua rau tus nqi ntawm cov tshuaj tiv thaiv txo. Cov tshuaj no ceev cov tshuaj tiv thaiv, yog li nce cov tshuaj tiv thaiv
Dab tsi cuam tshuam rau tus nqi ntawm cov tshuaj tiv thaiv quizlet?
Cov ntsiab lus hauv cov txheej txheem no (12) Plaub yam uas cuam tshuam rau tus nqi ntawm cov tshuaj tiv thaiv kab mob; kub. Kev sib tsoo txoj kev xav. Kub nce. Concentration nce. Txo Particle loj. Kev siv cov catalyst. Enzymes. Saib xyuas tus nqi ntawm cov tshuaj tiv thaiv
Yuav ua li cas cov khoom tsim tawm ib feeb cuam tshuam rau tus nqi ntawm cov tshuaj tiv thaiv enzyme catalyzed?
Rau ib qho enzyme catalyzed cov tshuaj tiv thaiv, tus nqi feem ntau yog qhia nyob rau hauv tus nqi ntawm cov khoom tsim tawm ib feeb. Thaum qhov kub thiab txias, qhov cua sov feem ntau nce tus nqi ntawm cov enzyme catalyzed cov tshuaj tiv thaiv vim tias cov reactants muaj zog ntau dua, thiab tuaj yeem ua tiav qhov ua kom muaj zog
Yam dab tsi cuam tshuam rau tus nqi ntawm cov tshuaj tiv thaiv tshuaj?
Cov yam ntxwv uas cuam tshuam rau cov tshuaj tiv thaiv yog: thaj tsam ntawm cov khoom reactant. concentration los yog siab ntawm ib tug reactant. kub. xwm ntawm cov reactants. muaj/tsis muaj catalyst
Dab tsi yog tshuaj lom neeg cov tshuaj tiv thaiv thiab cov tshuaj tiv thaiv lub cev?
Qhov sib txawv ntawm cov tshuaj tiv thaiv lub cev thiab cov tshuaj tiv thaiv tshuaj yog muaj pes tsawg leeg. Hauv cov tshuaj tiv thaiv tshuaj, muaj kev hloov pauv ntawm cov tshuaj hauv nqe lus nug; nyob rau hauv ib qho kev hloov ntawm lub cev muaj qhov sib txawv ntawm qhov tsos, tsis hnov tsw, los yog cov duab yooj yim ntawm cov qauv ntawm cov teeb meem yam tsis muaj kev hloov pauv hauv cov ntsiab lus
