Ib tus catalyst ua kom cov tshuaj tiv thaiv kab mob, tsis tas siv cov tshuaj tiv thaiv. Nws nce cov tshuaj tiv thaiv los ntawm txo qis lub zog ua kom rau cov tshuaj tiv thaiv. … Nco ntsoov tias nrog cov catalyst, qhov nruab nrab kinetic zog ntawm cov molecules tseem zoo li qub tab sis lub zog yuav tsum tau txo qis (Daim duab 7.13).
Puas catalyst nce lossis txo tus nqi ntawm cov tshuaj tiv thaiv?
Kev cuam tshuam ntawm catalysts. Tus nqi ntawm tawm tsam tuaj yeem nce ntxiv los ntawm kev ntxiv ib qho khoom siv tsim nyog. Lub catalyst yog ib yam khoom uas nce tus nqi ntawm cov tshuaj tiv thaiv tshuaj tab sis nws tsis siv (tseem tshuaj tsis hloov thaum kawg). Nws muab txoj hauv kev hloov pauv ntawm kev ua kom qis zog.
Catalyst cuam tshuam li cas cov tshuaj tiv thaiv?
Catalysts yog cov tebchaw uas ua kom tus nqi ntawm cov tshuaj tiv thaiv. Catalysts ua kom nrawm tawm tsam los ntawm kev txo lub zog ntawm tus nqi-txheej hloov lub xeev. Catalysts tsis cuam tshuam rau lub xeev sib npaug ntawm cov tshuaj tiv thaiv.
Qhov twg catalyst txo tus nqi ntawm cov tshuaj tiv thaiv?
Catalysts feem ntau ua kom cov tshuaj tiv thaiv los ntawm kev txo lub zog ua kom lub zog lossis hloov cov tshuaj tiv thaiv. Enzymes yog cov proteins uas ua cov catalysts hauv cov tshuaj biochemical. Cov hom catalysts muaj xws li enzymes, acid-base catalysts, thiab heterogeneous (los yog nto) catalysts.
Yuav ua li cas tsis zoo catalyst txo tus nqi ntawm cov tshuaj tiv thaiv?
Cov catalysts tsis zoo yog qhov muaj txiaj ntsig los ua kom qeeb lossis nres qhov tsis xav tau. - Hauv qhov tsis zoo catalysis tus nqi ntawm cov tshuaj tiv thaiv txo qis los ntawm kev ua kom lub zog ua kom muaj zog. Yog li, tus naj npawb ntawm cov reactant molecules uas tau hloov mus rau hauv cov khoom txo qis thiab li no tus nqi ntawm cov tshuaj tiv thaiv txo.

Cov tshuaj tiv thaiv dab tsi rau kev txhaj tshuaj tiv thaiv thib ob?
Cov tshuaj tiv thaiv COVID-19 thib ob yog dab tsi? Cov kev mob tshwm sim feem ntau tom qab koob thib ob yog qhov mob ntawm qhov chaw txhaj tshuaj (92.1% tshaj tawm tias nws kav ntev dua 2 teev); qaug zog (66.4%); mob lub cev lossis leeg nqaij (64.
Puas yog lub cev tiv thaiv kab mob hauv lub cev puas tsim cov tshuaj tiv thaiv?
Lub cev tiv thaiv kab mob tau txais, nrog kev pab los ntawm lub cev hauv lub cev, tsim cov hlwb (tshuaj tiv thaiv kab mob) los tiv thaiv koj lub cev los ntawm ib tus neeg invader tshwj xeeb. Cov tshuaj tiv thaiv no yog tsim los ntawm cov hlwb hu ua B lymphocytes tom qab lub cev tau raug rau cov neeg ua phem.
Vim li cas cov tshuaj tiv thaiv combustion yog cov tshuaj tiv thaiv oxidation?
Kev sib xyaw ua ke ib txwm ua rau muaj oxygen lossis huab cua. … Hauv combustion cov tshuaj tiv thaiv oxygen yog ua ke nrog cov roj qhov chaw feem ntau carbon thiab hydrogen raws li ua rau carbon dioxide thiab dej thiab yog li qhov no yog cov tshuaj tiv thaiv oxidation.
Puas kev tiv thaiv txo qis tom qab txhaj tshuaj tiv thaiv covid?
Cov kws tshaj lij tseem tsis tau paub tias kev tiv thaiv yuav kav ntev npaum li cas. Thaum cov kws tshawb fawb tau pom tias cov tshuaj tiv thaiv yuav tiv thaiv tib neeg feem ntau rau thawj ob peb lub hlis tom qab tau txais koob tshuaj thib ob, lawv tsis muaj ntaub ntawv hais txog kev tiv thaiv kab mob mus ntev uas cov tshuaj tiv thaiv no tuaj yeem muab.
Los ntawm qhov kev txiav txim ntawm enzymes tus nqi ntawm cov tshuaj tiv thaiv biochemical?
Enzymes yog cov khoom siv roj ntsha. Catalysts txo qis lub zog ua kom muaj zog rau cov tshuaj tiv thaiv. Qhov qis dua lub zog ua kom muaj zog rau cov tshuaj tiv thaiv, qhov nrawm dua. Yog li enzymes nrawm cov tshuaj tiv thaiv los ntawm kev ua kom lub zog qis.
