Yog tag nrho cov enzymes nyob rau hauv ib qho system yog khi rau substrate , ntxiv substrate molecules yuav tsum tau tos rau ib tug enzyme kom muaj nyob tom qab ua tiav cov tshuaj tiv thaiv. Qhov no txhais tau hais tias tus nqi ntawm cov tshuaj tiv thaiv yuav txo raws li enzyme concentration txo.

Ib yam li ib tug yuav nug, ua li cas substrate concentration cuam tshuam rau enzymes?

Thaum xub thawj, qhov nce hauv substrate concentration ua rau kom nce tus nqi ntawm ib qho enzyme - catalyzed cov tshuaj tiv thaiv. Raws li cov enzyme molecules ua saturated nrog substrate , qhov no nce nyob rau hauv cov tshuaj tiv thaiv theem tawm. Tus nqi ntawm ib enzyme -catalyzed cov tshuaj tiv thaiv nce ntxiv nrog rau kev nce ntxiv concentration ntawm ib enzyme.

Ib sab saum toj no, txo qis kev ua enzyme yog dab tsi? Inhibition ntawm kev ua haujlwm enzyme Qee yam khoom txo los yog txawm nres lub catalytic kev ua si ntawm cov enzymes hauv biochemical cov tshuaj tiv thaiv. Lawv thaiv lossis cuam tshuam lub vev xaib nquag. Cov tshuaj no hu ua inhibitors, vim hais tias lawv inhibit cov tshuaj tiv thaiv.

Kuj nug, kev siv cov enzyme qis dua cuam tshuam rau koj qhov kev sim li cas?

Raws li cov enzyme concentration txo qis, muaj tsawg cov enzymes kom yooj yim rau cov tshuaj tiv thaiv. yog li ntawd, tus nqi ntawm cov tshuaj tiv thaiv tshwm sim txo qis raws li tus naj npawb ntawm cov enzymes muaj peev xwm ua kom cov tshuaj tiv thaiv txo qis. ceev ntawm qhov cov enzymes react tsis yog cuam tshuam los ntawm concentration.

Kev sib raug zoo ntawm enzyme concentration thiab kev ua enzyme yog dab tsi?

Cov kev sib raug zoo ntawm kev ua thiab concentration cuam tshuam los ntawm ntau yam xws li kub, pH, thiab lwm yam. Ib enzyme assay yuav tsum tau tsim kom cov kev soj ntsuam kev ua si yog proportional rau tus nqi ntawm enzyme tam sim no nyob rau hauv kev txiav txim hais tias lub enzyme concentration tsuas yog qhov txwv tsis pub muaj.
