Enzyme catalysis kuaj pom los ntawm kev ntsuas qhov pom ntawm cov khoom lossis ploj ntawm cov reactants. Rau ntsuas ib yam, koj yuav tsum muaj peev xwm pom nws. Enzyme kev ntsuam xyuas yog cov kev xeem tsim los rau ntsuas kev ua haujlwm enzyme los ntawm kev ntsuas qhov kev hloov pauv hauv qhov concentration ntawm cov khoom uas kuaj tau.
Tib neeg kuj nug, qhov twg hauv qab no tuaj yeem cuam tshuam tus nqi ntawm cov tshuaj tiv thaiv enzyme catalyzed?
Ob peb yam cuam tshuam rau tus nqi uas enzymatic cov tshuaj tiv thaiv ua - kub, pH, enzyme concentration, substrate concentration, thiab muaj cov inhibitors lossis activators.
Qhov thib ob, qhov piv txwv ntawm cov tshuaj tiv thaiv enzyme catalyzed yog dab tsi? Cov cov tshuaj tiv thaiv yog: Oxidation thiab txo. Enzymes uas ua cov no cov tshuaj tiv thaiv hu ua oxidoreductases. Rau piv txwv , cawv dehydrogenase hloov cov cawv thawj rau aldehydes.
Dhau li ntawm qhov no, dab tsi yog enzyme catalysed cov tshuaj tiv thaiv?
Enzyme catalysed cov tshuaj tiv thaiv tshwm sim ntawm ib qho chaw tshwj xeeb ntawm qhov chaw loj enzyme molecule hu ua active site (raws li nyob rau hauv heterogeneous catalysts). Lub reactant molecule, feem ntau hu ua lub substrate, muaj peev xwm tsim tau kuj tsis muaj zog, ib ntus daim ntawv cog lus rau lub enzyme ntawm qhov chaw nquag.
Koj ntsuas kev ua enzyme li cas?
Kev ua haujlwm enzyme = moles ntawm substrate hloov dua siab tshiab rau ib chav tsev lub sij hawm = tus nqi × cov tshuaj tiv thaiv ntim. Kev ua haujlwm enzyme yog a ntsuas ntawm qhov ntau ntawm active enzyme tam sim no thiab yog li nyob ntawm tej yam kev mob, uas yuav tsum tau teev.

Dab tsi tuaj yeem siv los tswj tus nqi ntawm cov tshuaj tiv thaiv hauv lub tshuab hluav taws xob nuclear?
Cov rods tswj tau siv nyob rau hauv nuclear reactors los tswj lub fission tus nqi ntawm uranium los yog plutonium. Lawv cov khoom muaj xws li tshuaj lom neeg xws li boron, cadmium, nyiaj, lossis indium, uas muaj peev xwm nqus tau ntau cov neutrons yam tsis muaj fissioning
Yam dab tsi tuaj yeem hloov pauv yog tias koj xav nce 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
Koj ntsuas tus nqi ntawm cov tshuaj tiv thaiv enzyme catalyzed li cas?
Enzyme catalysis yog kuaj pom los ntawm kev ntsuas qhov pom ntawm cov khoom lossis ploj ntawm cov reactants. Txhawm rau ntsuas qee yam, koj yuav tsum muaj peev xwm pom nws. Enzyme assay yog cov kev ntsuam xyuas tsim los ntsuas kev ua haujlwm ntawm enzyme los ntawm kev ntsuas qhov kev hloov pauv hauv cov ntsiab lus ntawm cov tshuaj uas pom tau
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
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
