yog vim li cas dej molecule tseem ceeb heev rau cov kab mob ? cov dej ua raws li cov kuab tshuaj rau cov tshuaj tiv thaiv kab mob thiab tseem pab thauj cov tshuaj yaj hauv thiab tawm ntawm lub hlwb. lub npe muab rau kom muaj peev xwm ntawm ib qho kev daws teeb meem aqueous rau neutralize. bing acidic los yog yooj yim daws yuav ua rau lawv mus rau denature.
Kuj nug, vim li cas cov dej molecule tseem ceeb rau cov kab mob?
Dej yog "Universal Solvent" Raws li ib tug polar molecule , dej interacts zoo tshaj plaws nrog rau lwm yam polar molecules , xws li nws tus kheej. Lub cohesion ntawm dej molecules pab cov nroj tsuag noj dej ntawm lawv cov hauv paus hniav. Cohesion kuj pab tau cov dej kub kub taw tes, uas pab tsiaj tswj lub cev kub.
Ib tug kuj yuav nug, vim li cas dej thiaj tseem ceeb rau cov hlwb? Dej yog tseem ceeb rau cov hlwb vim yog tsis muaj nws lawv yuav tsis muaj peev xwm tshem tawm cov khib nyiab, nqa cov as-ham lossis thauj oxygen. Nws pab txhawm rau rhuav tshem cov khoom pov tseg thiab cov khoom noj hauv lub cev cell ua tias lawv tuaj yeem txav mus los ntawm ntau cov membranes thiab cov lim dej hauv lub cev.
Li no, 5 yam dej num uas tseem ceeb rau lub neej yog dab tsi?
Cov khoom tseem ceeb ntawm cov dej yog nws cov polarity, cohesion, adhesion, nto nro, siab tshwj xeeb kub , thiab evaporative txias.
Dab tsi ions tsim thaum dej dissociates?
Kev sib cais dej thiab pH. Ib qho cuab yeej zoo kawg nkaus ntawm cov ntshiab dej yog nws dissociates rau daim ntawv hydrogen ions (H3O+) thiab hydroxide (OH-) ions.

Yuav ua li cas yog vim li cas tus qauv ntawm ib qho enzyme tseem ceeb heev rau nws txoj haujlwm hauv cov khoom muaj sia?
Enzymes ua kom cov tshuaj tiv thaiv uas tshwm sim hauv cov hlwb. Qhov kev ua haujlwm no cuam tshuam ncaj qha rau lawv cov qauv, nrog rau txhua qhov enzyme tau tshwj xeeb zoo li tus ua kom muaj zog rau ib qho tshuaj tiv thaiv. Kev poob ntawm cov qauv ua rau poob haujlwm. - Kub, pH, thiab kev tswj cov molecules tuaj yeem cuam tshuam rau kev ua haujlwm ntawm cov enzymes
