Catalase yog ib qho tseem ceeb enzyme uas siv hydrogen peroxide, ib qho nonradical ROS, raws li nws cov substrate. Cov enzyme no yog lub luag haujlwm rau kev ua kom tsis zoo los ntawm kev sib cais ntawm hydrogen peroxide, yog li tswj hwm qib zoo ntawm cov molecule hauv cell uas tseem yog qhov tseem ceeb rau cov txheej txheem ntawm tes.
Dab tsi yog qhov ua haujlwm ntawm catalase quizlet?
Catalase yog ib qho enzyme uas muaj nyob hauv yuav luag txhua yam kab mob uas muaj sia nyob tau raug oxygen (xws li kab mob, nroj tsuag, thiab tsiaj txhu). Nws catalyzes (ua rau lossis nrawm cov tshuaj tiv thaiv) decomposition ntawm hydrogen peroxide rau dej thiab oxygen.
catalase ua haujlwm nyob qhov twg?
Catalase yog ib qho enzyme nyob rau hauv lub siabuas zom cov teeb meem hydrogen peroxide rau hauv oxygen thiab dej.
Tus qauv thiab kev ua haujlwm ntawm catalase yog dab tsi?
1.6) yog ib qho enzyme uas muaj nyob rau hauv cov peroxisomes ntawm mammalian hlwb. Nws yog ib qho tetrameric enzyme uas muaj plaub zoo tib yam, tetrahedrally teem subunits ntawm 60 kDa, txhua tus muaj nyob rau hauv nws qhov chaw ua haujlwm ib pawg heme thiab NADPH. Catalase muaj ob txoj haujlwm enzymatic nyob ntawm qhov concentration ntawm H2O2.
Lub luag haujlwm tseem ceeb ntawm catalase hauv tib neeg yog dab tsi?
Raws li tau hais dhau los, lub luag haujlwm tseem ceeb ntawm catalase yog qhov decomposition ntawm hydrogen peroxide rau hauv dej thiab oxygen (catalytic kev ua si) Ntxiv mus, nws paub tias catalase tuaj yeem oxidize qis molecular hnyav. cawv nyob rau hauv lub xub ntiag ntawm tsawg concentrations H2O2 (kev ua haujlwm peroxidative).
