Catalase yog ib qho enzyme nyob rau hauv daim siab uas zom cov teeb meem hydrogen peroxide rau hauv oxygen thiab dej. Thaum cov tshuaj tiv thaiv no tshwm sim, cov pa oxygen npuas khiav thiab tsim ua npuas ncauj. Ua kom tiav txhua qhov chaw uas lub siab nyoos kov thaum lub sijhawm ua haujlwm no.
Hauv qhov no, dab tsi ua rau cov npuas tsim thaum koj ntxiv cov catalase rau hydrogen peroxide?
Thaum lub siab sib xyaw ua ke raug rau hydrogen peroxide , cov catalase enzyme nyob rau hauv daim siab reacts nrog lub hydrogen peroxide rau daim ntawv oxygen gas, uas tsim kom pom npuas hauv daim duab no, thiab dej.
vim li cas npuas tsim nyob rau hauv ib tug zoo catalase kuaj? npuas yog a zoo tshwm sim rau lub xub ntiag ntawm catalase . Cov kev kuaj catalase kuaj rau lub xub ntiag ntawm catalase , ib qho enzyme uas zom cov khoom tsis zoo hydrogen peroxide rau hauv dej thiab oxygen. Yog lub cev muaj peev xwm tsim catalase , nws yuav tsim npuas cov pa oxygen thaum ntxiv hydrogen peroxide rau nws.
Hais txog qhov no, dab tsi ua rau tsim npuas yog tias muaj catalase?
Cov enzyme catalase decomposes hydrogen peroxide rau hauv dej (H2O) thiab oxygen gas (O2). Cov pa oxygen yog dab tsi ua rau npuas . Thaum twg hydrogen peroxide yog siv rau lub qhov txhab, nws npuas vim cov qe ntshav, nrog rau cov kab mob uas kis rau lub qhov txhab, tsim catalase.
Vim li cas catalase poob ntawm 80 C?
Cov catalase ua tsis tiav ua 80 ° C vim nws muaj tshaj nws qhov kev ua haujlwm kub zoo rau qhov ua rau lub enzyme ua kom puas. Cov enzyme muaj nuj nqi nce ua ntej nws tau saturated nrog substrate vim nws tseem tsis tau muaj txaus substrate kom saturate tag nrho cov enzymes.

Dab tsi yog daim duab npuas hauv kev tsim sab hauv?
Los ntawm kev txhais, daim duab npuas yog ib daim duab kos duab dawb ua los ntawm architects thiab cov tsim sab hauv los siv rau kev npaj chaw thiab koom haum nyob rau theem ua ntej ntawm tus txheej txheem tsim. Daim duab npuas yog qhov tseem ceeb vim tias cov theem tom qab ntawm cov txheej txheem tsim yog raws li lawv
Koj puas ntxiv cov kua qaub rau hauv lub hauv paus lossis lub hauv paus rau cov kua qaub?
Ntxiv cov kua qaub ua kom cov concentration ntawm H3O + ions hauv cov tshuaj. Ntxiv ib lub hauv paus txo cov concentration ntawm H3O + ions hauv cov tshuaj. Cov kua qaub thiab lub hauv paus zoo li cov tshuaj tiv thaiv. Yog hais tias lub hauv paus yog ntxiv rau cov kua qaub, cov tshuaj yuav tsis acidic thiab txav mus rau nruab nrab ntawm pH nplai
Dab tsi ua rau DNA tshiab strand los ntawm kev ntxiv cov hauv paus ntxiv?
Glossary DNA ligase: cov enzyme uas catalyzes koom nrog DNA tawg ua ke. DNA polymerase: ib qho enzyme uas tsim cov strand tshiab ntawm DNA ntxiv rau cov qauv strand. helicase: ib qho enzyme uas pab qhib DNA helix thaum DNA replication los ntawm kev rhuav tshem cov hydrogen bonds
Dab tsi ua rau cov npuas tsim thaum koj ntxiv cov hydrochloric acid rau zinc hlau?
Mercuric oxide. Mercury hlau. Thaum zincreacts nrog hydrochloric acid, cov tshuaj tiv thaiv bubblesvigorously li hydrogen gas yog tsim. Thaum zinc reacts nrog hydrochloric acid, lub raj kuaj ua kom sov asenergy yog tso tawm thaum lub sij hawm cov tshuaj tiv thaiv
Dab tsi ua rau cov kaum sab nrauv ntxiv ntxiv rau?
Yog hais tias lub transversal txiav hla cov kab sib txuas (cov ntaub ntawv li niaj zaus) ces cov ces kaum sab nrauv yog ntxiv (ntxiv rau 180 °). Yog li hauv daim duab saum toj no, thaum koj txav cov ntsiab lus A lossis B, ob lub kaum sab xis qhia ib txwm ntxiv rau 180 °
