Cov induced haum qauv piav qhia txog kev tsim ntawm E-S complex raws li kev sib cuam tshuam ntawm cov substrate thiab ib qho chaw hloov tau yooj yim. Lub substrate tsim cov kev hloov hauv kev sib haum xeeb ntawm cov enzyme aligning kom zoo cov pab pawg hauv cov enzyme. Nws tso cai rau kev khi zoo dua thiab cov teebmeem catalytic.

Raws li qhov tshwm sim, tus qauv tsim qauv ua haujlwm zoo li cas?

Cov Induced - Haum Qauv Lub xauv-thiab-tus yuam sij qauv hais tias lub substrate ua raws li 'tus yuam sij' rau 'xauv' ntawm qhov chaw nquag. Qhov kev xav no tswj xyuas qhov chaw nquag thiab cov substrate yog , pib, tsis zoo tag nrho kev sib tw rau ib leeg. Es tsis txhob, lub substrate induces ib tug hloov ntawm cov duab nyob rau hauv lub enzyme.

Tsis tas li ntawd, vim li cas qhov kev ua ntawm ib qho enzyme hu ua kev ntxias kom haum? allosteric tswj … lub hauv paus ntawm so- hu ua induced-fit txoj kev xav, uas hais tias kev khi ntawm ib lub substrate los yog lwm yam molecule rau ib enzyme ua rau muaj kev hloov pauv ntawm cov duab enzyme thiaj li txhim kho lossis inhibit nws kev ua si.

Tom qab ntawd, tus qauv induced haum txhais li cas?

Cov induced haum qauv yog ib qauv rau kev sib cuam tshuam ntawm enzyme-substrate. Nws piav qhia tias tsuas yog qhov tsim nyog substrate yog muaj peev xwm inducing txoj kev sib raug zoo ntawm qhov chaw active uas yuav pab kom lub enzyme ua nws txoj haujlwm catalytic. Cov induced haum qauv pom zoo los ntawm Daniel Koshland hauv 1958.

Dab tsi yog qhov induced haum hypothesis ntawm enzyme?

Ib qho qauv tsis ntev los no, uas yog rov qab los ntawm cov pov thawj, thiab tau txais dav dav raws li piav qhia txoj hauv kev cov enzymes ua haujlwm, yog Induced - Fit Hypothesis . Nws hais tias cov duab ntawm Active Sites tsis raws nraim Complementary, tab sis hloov cov duab nyob rau hauv lub xub ntiag ntawm ib tug tshwj xeeb substrate los ua Complementary.
