Catalysts txo qis lub zog ua kom muaj kev cuam tshuam. Qhov qis dua lub zog ua kom muaj zog rau cov tshuaj tiv thaiv, qhov nrawm dua. Yog li enzymes ceev cov tshuaj tiv thaiv los ntawm kev ua kom lub zog qis.
Catalyst cuam tshuam li cas cov tshuaj tiv thaiv?
Catalysts tuaj yeem txo qhov ua kom lub zog thiab nce cov tshuaj tiv thaivyam tsis tau noj hauv cov tshuaj tiv thaiv. … Molecules koom nrog cov ntawv cog lus muaj zog yuav muaj cov tshuaj tiv thaiv qis dua li cov molecules koom los ntawm cov ntawv cog lus tsis muaj zog, vim tias muaj zog ntau ntxiv uas yuav tsum tau rhuav tshem cov ntawv cog lus muaj zog.
Pob catalysts qeeb lub sij hawm cov tshuaj tiv thaiv?
Lub cev lub cev ntawm reactants. Hmoov hnov mob sai dua li cov blocks - thaj tsam ntau dua thiab txij li cov tshuaj tiv thaiv tshwm sim ntawm qhov chaw peb tau txais tus nqi nrawm dua. Lub xub ntiag (thiab concentration / lub cev daim ntawv) ntawm lub catalyst (los yog inhibitor). Lub catalyst ua kom cov tshuaj tiv thaiv, tus inhibitor qeeb nws.
Dab tsi yog qhov catalyst tshaj plaws?
A catalyst yog ib yam uas pab cov txheej txheem tshuaj. Cov catalyst tshaj plaws yog heat, tab sis qee zaum cov catalyst yog ib yam khoom uas pab txhawb cov txheej txheem yam tsis muaj kev hloov pauv nws tus kheej. Nyiaj yog ib qho khoom siv rau ntau qhov kev tsim khoom, feem ntau tsim cov khoom uas koj siv txhua hnub.
Yuav ua li cas yog tias 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 tsis thoob 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."
