Ib immobilized enzyme yog ib enzyme txuas mus rau ib qho inert, insoluble khoom-xws li calcium alginate (tsim los ntawm reacting ib tug sib tov ntawm sodium alginate tov thiab enzyme daws nrog calcium chloride). Qhov no tuaj yeem ua rau muaj zog tiv thaiv kev hloov pauv hauv cov xwm txheej xws li pH lossis kub.
Yog li ntawd, dab tsi yog txhais los ntawm immobilization?
: kev act immobilizing los yog lub xeev ntawm kev ua immobilized :as. a: nyob ntsiag to so hauv txaj rau lub sij hawm ntev siv los kho cov kab mob (raws li tuberculosis) b: fixation (raws li los ntawm plaster cam khwb cia) ntawm ib feem ntawm lub cev feem ntau los txhawb kev kho nyob rau hauv ib txwm muaj kev sib raug zoo.
Ib yam li ntawd, enzyme immobilization cuam tshuam li cas rau enzyme kinetics? Immobilisation ua tau zoo heev nyhuv stability ntawm ib enzyme . Yog tias immobilisation txheej txheem qhia txhua yam strain rau hauv enzyme , qhov no yuav txhawb kom inactivation ntawm lub cov enzymes nyob rau hauv denaturing tej yam kev mob (piv txwv li, siab dua kub los yog heev ntawm pH).
Raws li txoj cai, cov txheej txheem ntawm enzyme immobilization yog dab tsi?
Kev lig kev cai, plaub txoj kev yog siv rau enzyme immobilization , uas yog (1) non-covalent adsorption thiab deposition, (2) lub cev entrapment, (3) covalent attachment, thiab (4) bio-conjugation (Fig. 2). Kev txhawb nqa kev khi tuaj yeem yog lub cev lossis tshuaj lom neeg, suav nrog cov nyiaj tsis muaj zog lossis covalent bonds.
Vim li cas immobilized enzymes ruaj khov dua?
Qhov nce ruaj khov tej zaum yuav tshwm sim los ntawm qhov tseeb tias immobilization txwv lub thermal txav ntawm lub enzyme ntawm qhov kub siab dua. Yog li ntawd, thermal denaturation yuav tsis tshwm sim ntawm qhov kub siab dua nrog ib qho immobilized enzyme.

Dab tsi yog txhais los ntawm kab lus kab ke ntawm kev txheeb xyuas thiab sib npaug?
Kev txhais cov tshev thiab tshuav nyiaj li cas: cov txheej txheem uas tso cai rau txhua ceg ntawm tsoomfwv los hloov lossis txwv tsis pub ua ntawm lwm ceg kom tiv thaiv ib ceg twg los ntawm kev siv lub zog ntau dhau
Dab tsi yog txhais los ntawm lub tsev qiv ntawv ntawm cov ntaub ntawv keeb kwm hais txog biodiversity?
Dab tsi yog txhais los ntawm 'natural library' ntawm genetic information in reference to biodiversity? Txhua yam kab mob muaj sia muaj cov ntaub ntawv caj ces uas tib neeg tuaj yeem tshawb nrhiav. Kev siv cov peev txheej ib puag ncig hauv txoj hauv kev uas tsis ua rau muaj kev puas tsuaj rau ib puag ncig mus ntev yog zoo li. siv nyiaj ntau npaum li koj khwv tau
Lub ntsiab lus ntawm immobilization yog dab tsi?
: txoj cai ntawm immobilizing los yog lub xeev ntawm immobilized: as. a: nyob ntsiag to so hauv txaj rau lub sijhawm ntev siv los kho cov kab mob (raws li tuberculosis) b: kho (raws li plaster cam) ntawm lub cev feem ntau los txhawb kev kho mob hauv cov qauv kev sib raug zoo
Dab tsi yog qhov txawv ntawm qhov rov qab los ntawm peev thiab rov qab los ntawm peev?
Ua ntej, qee qhov kev txhais. Rov qab los ntawm peev ntsuas qhov rov qab uas qhov kev nqis peev ua rau cov neeg koom nrog peev. Rov qab los ntawm peev (thiab ntawm no Idiffer nrog qee cov ntsiab lus) yog thaum tus neeg ua lag luam tau txais ib feem ntawm nws cov peev txheej qub rov qab - suav nrog cov nyiaj tau los ntawm cov nyiaj tau los - los ntawm kev nqis peev
Dab tsi ntawm cov hauv qab no yog lub ntsiab lus zoo tshaj plaws ntawm ib qho enzyme?
