Hauv peb qhov xwm txheej, lub enzyme yog catalase, lub substrate yog hydrogen peroxide, thiab cov tshiab tsim tebchaw yog oxygen gas thiab dej.
Tsis tas li ntawd, puas catalase khi rau lub substrate uas tsis yog hydrogen peroxide?
Enzymes hauv lub cev Luckily, muaj ib enzyme uas pab neutralize oxidative tebchaw zoo li hydrogen peroxide . Cov enzyme catalase pab tiv thaiv lub cev los ntawm oxidative cell puas los ntawm kev tawg hydrogen peroxide rau dej thiab oxygen. Ib qho enzyme muaj ib qho chaw ua haujlwm rau cov ntsiab lus tshwj xeeb txuas.
Tsis tas li ntawd, dab tsi yog qhov reagent uas ua haujlwm raws li lub substrate hauv kev sim catalase?
Tib neeg kuj nug, tus qauv ntawm catalase yog dab tsi?
Catalase (EC 1.11. 1.6) yog ib qho enzyme uas muaj nyob rau hauv cov peroxisomes ntawm mammalian hlwb. Nws yog ib tug tetrameric enzyme uas muaj plaub zoo tib yam, tetrahedrally teem subunits ntawm 60 kDa, txhua tus muaj nyob rau hauv nws active chaw ib heme pawg thiab NADPH.
Dab tsi yog cov substrate thiab cov khoom ntawm cov tshuaj tiv thaiv catalysed los ntawm catalase?
Cov tshuaj uas enzymes ua rau yog hu ua substrate thiab cov khoom tsim tau raug hu ua cov khoom . Hauv qhov piv txwv no, enzyme catalase ua rau ntawm substrate hydrogen peroxide los ua cov tshuaj cov khoom dej thiab oxygen.

Cov mis rau catalase yog dab tsi?
Catalase yog ib qho enzyme uas catalyzes decomposition ntawm hydrogen peroxide. Lub npe system ntawm 2H2O2 - → 2H2O + O2 yog H2O2; H2O2 yog oxidoreductase (E, C, 1, 11, 1, 6). Nws cofactor yog heme thiab molecular hnyav yog 250,000, uas twb muaj lawm nyob rau hauv daim ntawv ntawm tetramer. Catalase muaj nyob rau hauv yuav luag tag nrho cov tsiaj hlwb
Dab tsi yog qhov tseem ceeb tshaj plaws uas yuav tsum muaj rau cov kua dej ntws hauv cov kav dej Dab tsi lwm yam cuam tshuam rau cov dej ntws?
Thaum ib qho kev quab yuam sab nraud yog exerted rau ntawm cov kua uas muaj, qhov tshwm sim siab yog kis sib npaug thoob plaws hauv cov kua. Yog li txhawm rau kom dej ntws, dej xav tau qhov sib txawv siab. Cov kav dej kuj tuaj yeem cuam tshuam los ntawm cov kua dej, cov yeeb nkab loj, qhov kub thiab txias (cov kav dej khov), cov kua dej ntom ntom
Dab tsi yog kev sib raug zoo ntawm lub substrate thiab catalyst?
Lub catalyst yog ib yam tshuaj uas ua rau kom tus nqi ntawm cov tshuaj tiv thaiv tsis muaj nws tus kheej raug hloov los ntawm cov tshuaj tiv thaiv. Qhov tseeb tias lawv tsis hloov pauv los ntawm kev koom tes hauv cov tshuaj tiv thaiv qhov txawv ntawm cov catalysts los ntawm substrates, uas yog cov reactants uas catalysts ua haujlwm. Enzymes catalyze cov tshuaj tiv thaiv biochemical
Dab tsi yog qhov substrate hauv enzyme catalysis lab?
Enzymes catalyze cov tshuaj tiv thaiv los ntawm kev txo qis lub zog ua kom tsim nyog rau qhov tshwm sim tshwm sim. Lub molecule uas ib qho enzyme ua rau yog hu ua substrate. Hauv cov tshuaj tiv thaiv enzyme-mediated, substrate molecules raug hloov, thiab cov khoom tsim
Lub substrate nyob rau hauv cov tshuaj tiv thaiv no yog dab tsi?
Nyob rau hauv biochemistry, lub substrate yog ib tug molecule raws li ib tug enzyme ua. Enzymes catalyze cov tshuaj tiv thaiv nrog rau cov substrate. Nyob rau hauv cov ntaub ntawv ntawm ib tug substrate, lub substrate bonds nrog lub enzyme active site, thiab ib tug enzyme-substrate complex yog tsim
