Ib enzyme yog ib qho protein nyob rau hauv lub cell uas txo qis lub zog ua kom muaj zog ntawm cov tshuaj tiv thaiv catalyzed, yog li ua rau tus nqi ntawm cov tshuaj tiv thaiv. Nyob rau hauv thiaj li yuav sim rau lub xub ntiag ntawm lub enzyme , cov extract yog tov nrog H2 O + O2 thiab ib tug compound feem ntau hu ua Guiacol (2-methyoxyphenol).
Hauv qhov no, puas yog peroxidase ib qho enzyme?
Peroxidase yog ib enzyme pom nyob rau hauv ntau yam kab mob, los ntawm cov nroj tsuag mus rau tib neeg mus rau cov kab mob. Nws txoj haujlwm yog txhawm rau txhawm rau hydrogen peroxide (H2O2), uas yog ib qho ntawm cov co toxins uas ua los ntawm kev siv oxygen rau kev ua pa. (Qhov tseeb tias nws muaj tshuaj lom yog dab tsi ua rau hydrogen peroxide pab tau hauv cov khoom siv pab thawj zaug.
Tom qab ntawd, lo lus nug yog, dab tsi cuam tshuam rau enzyme kev ua haujlwm lab? Ob peb yam cuam tshuam rau tus nqi ntawm cov tshuaj tiv thaiv enzymatic mus - kub , pH enzyme concentration, substrate concentration, thiab muaj cov inhibitors lossis activators.
Tsis tas li ntawd, vim li cas guaiacol thiaj li tsim nyog ua lub substrate rau peroxidase?
Hmoov zoo, cov hlwb muaj enzyme, peroxidase uas sai sai tawg hydrogen peroxide rau hauv dej thiab oxygen, tiv thaiv cellular puas. Cov tshuaj tiv thaiv no yuav ua ke nrog cov tshuaj tiv thaiv zas xim guaiacol , uas hloov los ntawm tsis muaj xim mus rau xim av raws li nws yog oxidized los ntawm enzyme peroxidase nyob rau hauv lub xub ntiag ntawm H2O2.
Nws txhais li cas rau denature ib enzyme?
Ib enzyme yog ib qho protein ntau molecule ua los ntawm ntau txhiab amino acids. Thaum twg cov enzymes denature , lawv tsis ua haujlwm thiab tsis tuaj yeem ua haujlwm. Qhov kub thiab txias tsis zoo ntawm pH - qhov ntsuas ntawm cov tshuaj acidity lossis alkalinity - tuaj yeem ua rau cov enzymes ua denatured.

Dab tsi yog saturation kinetics ntawm ib qho enzyme?
Txawm li cas los xij, tsis zoo li cov tshuaj tiv thaiv tsis muaj tshuaj lom neeg, cov tshuaj tiv thaiv enzyme-catalysed tso saib saturation kinetics. Ob qho tseem ceeb tshaj plaws kinetic zog ntawm ib qho enzyme yog yooj yim npaum li cas cov enzyme ua saturated nrog ib qho substrate, thiab qhov siab tshaj plaws nws tuaj yeem ua tiav
Puas yog ib qho tsis muaj polar molecule puas muaj hydrogen bonding?
Yog hais tias lub molecule tsis yog polar, ces tsis muaj kev sib cuam tshuam dipole-dipole los yog hydrogen bonding tuaj yeem tshwm sim thiab tsuas yog ua tau intermolecular quab yuam yog lub zog van der Waals tsis muaj zog
Dab tsi yog lwm lo lus rau ib qho enzyme?
Lub npe enzyme feem ntau muab los ntawm nws cov substrate los yog cov tshuaj tiv thaiv nws catalyzes, nrog rau lo lus xaus hauv -ase. Piv txwv li lactase, cawv dehydrogenase thiab DNA polymerase. Cov enzymes sib txawv uas catalyze tib cov tshuaj tiv thaiv yog hu ua isozymes
Puas yog ib qho enzyme A organic lossis inorganic catalyst?
Enzymes thiab catalysts ob leeg cuam tshuam tus nqi ntawm cov tshuaj tiv thaiv. Qhov sib txawv ntawm cov catalysts thiab enzymes yog cov enzymes feem ntau cov organic nyob rau hauv cov xwm thiab yog bio-catalysts, thaum uas tsis yog-enzymatic catalysts yuav ua inorganic tebchaw. Tsis yog cov catalysts lossis enzymes tau noj hauv cov tshuaj tiv thaiv lawv catalyze
Dab tsi yog ib qho kev qhia uas muaj tsawg kawg yog ib qho kev sib txawv?
Algebraic qhia ?: Cov lus lej suav nrog tsawg kawg ib qho sib txawv thiab qee zaum tus lej thiab cov cim ua haujlwm
