Catalysts nrawm cov tshuaj tiv thaiv los ntawm kev txo qis ntawm lub zog koj xav tau kom tau txais ib qho mus Catalysis yog lub caj qaum ntawm ntau cov txheej txheem kev lag luam, uas siv tshuaj lom neeg los tig cov ntaub ntawv raw. rau hauv cov khoom muaj txiaj ntsig. Catalysts yog ib qho tseem ceeb hauv kev ua cov yas thiab ntau lwm yam khoom tsim.
Vim li cas thiaj xav tau catalyst rau tshuaj tiv thaiv?
Ib tus catalyst yog ib yam khoom uas ua kom muaj tshuaj lom neeg, lossis txo qhov kub lossis siab xav tau los pib ib qho, tsis tas siv nws tus kheej thaum lub sijhawm tshuaj tiv thaiv. … Vim li ntawd, cov catalysts ua kom yooj yim rau cov atoms kom tawg thiab tsim cov tshuaj sib txuas los tsim cov kev sib txuas tshiab thiab cov tshuaj tshiab
Vim li cas cov catalysts tseem ceeb rau kev lag luam?
Qhov txiaj ntsig ntawm catalysts hauv lub ntiaj teb kev lag luam yog qhov tseem ceeb. Catalysts ua cov txheej txheem tshuaj lom neeg muaj kev nyab xeeb, yooj yim dua, thiab nrawm duaLawv ua tiav qhov no los ntawm kev tswj hwm lub zog ua kom muaj zog los pib cov tshuaj tiv thaiv. … Cov no yog txhua yam tseem ceeb rau kev lag luam vim nws ua rau cov nqi ntau lawm sai dua.
Yuav ua li cas yog tsis muaj catalyst?
"Yog tsis muaj catalysts, yuav tsis muaj txoj sia nyob, los ntawm microbes mus rau tib neeg, "nws hais. "Nws ua rau koj xav paub tias kev xaiv ntuj ua haujlwm li cas los tsim cov protein uas tawm hauv av los ua cov txheej txheem tseem ceeb rau cov tshuaj tiv thaiv qeeb heev. "
Yuav ua li cas tshwm sim yam tsis muaj catalyst?
Catalysts ua kom tus nqi ntawm cov tshuaj tiv thaiv, tab sis lawv tsis hloov txoj hauj lwm ntawm qhov sib npaug ntawm cov tshuaj tiv thaiv. Yog tias tsis muaj cov catalyst koj cov tshuaj tiv thaiv yuav mus ua tiav(tag nrho rau cov khoom), txawm tias qeeb heev, ces yog, nyob rau hauv lub xub ntiag ntawm catalysts, cov reactants yuav tig mus rau hauv cov khoom.
