Catalytic decomposition ntawm hydrogen peroxide tshwm sim thaum siv rau qhov txhab. Catalase, ib qho enzyme hauv cov ntshav, catalyzes cov tshuaj tiv thaiv.

Dab tsi yog qhov sib xyaw zoo tshaj plaws catalyzes decomposition ntawm peroxide?

Manganese oxide (MnO2) yog siv dav hauv cov tshuaj tiv thaiv heterogeneous ntawm decomposition ntawm hydrogen peroxide ua tsaug rau nws cov catalytic efficiency hauv cov tshuaj tiv thaiv no. Nws feem ntau yog siv rau hauv daim ntawv ntawm cov hmoov ua tsaug rau nws qhov kev sib cuag siab heev [21].

Dab tsi enzyme catalyzes kev tawg ntawm hydrogen peroxide rau oxygen thiab dej?

Ib daim ntawv ua npuas ncauj thaum cov npuas ntawm cov pa ntim rau hauv cov kua lossis cov khoom. Hauv qhov no, cov pa oxygen tsim tawm thaum hydrogen peroxide tawg rau hauv oxygen thiab dej ntawm kev sib cuag nrog catalase, ib qho enzyme pom hauv daim siab. Enzymes yog cov protein molecules tshwj xeeb uas ua rau muaj tshuaj lom neeg.

Tus neeg sawv cev dab tsi yog hydrogen peroxide?

Hydrogen peroxide muaj cov tshuaj formula H2O2 thiab yog oxidizing agent uas zoo ib yam li cov pa oxygen tab sis muaj zog heev. Kev ua oxidizing ntawm hydrogen peroxide tshwm sim los ntawm qhov muaj cov pa oxygen ntxiv piv nrog cov qauv dej.

Qhov tsis zoo ntawm hydrogen peroxide yog dab tsi?

Qhov tsis zoo ntawm hydrogen peroxide yog: Nws yog ib qho muaj zog oxidizer thiab tuaj yeem ua rau muaj ntau yam tshuaj. Thaum ntsib nrog qhov muag,nws ua rau khaus. Hydrogen peroxide maj mam decomposes rau hauv dej thiab oxygen.
