Cov khoom hnyav ntawm dej txhais tau hais tias ntau yam sib txawv tuaj yeem yaj hauv nws vim nws qhov polarity. Qhov no tso cai rau cov khoom nqa mus rau hauv cov ntshav thiab kua txiv ntawm cov nroj tsuag thaum lawv yaj hauv dej . Nws kuj ua dej yog qhov nruab nrab zoo rau cov tshuaj tiv thaiv metabolic.

Hais txog qhov no, vim li cas dej yog qhov nruab nrab zoo rau cov tshuaj tiv thaiv?

Dej yog ib qho zoo tagnrho nruab nrab rau cov tshuaj tiv thaiv Raws li nws tuaj yeem khaws cov cua kub ntau, yog hluav taws xob nruab nrab, thiab muaj pH ntawm 7.0, txhais tau tias nws tsis yog acidic lossis yooj yim. Ntxiv thiab, dej muaj feem xyuam rau ntau yam enzymatic cov tshuaj tiv thaiv Raws li tus neeg sawv cev los rhuav tshem cov ntawv cog lus lossis, los ntawm nws qhov kev tshem tawm ntawm lub cev, tsim cov ntawv cog lus.

Ib tug kuj yuav nug, vim li cas dej thiaj li zoo metabolite? Cov kab mob muaj sia nyob xav tau dej kom ciaj sia. Lwm yam kab mob xav tau dej txhawm rau zom cov zaub mov molecules lossis tsim lub zog thaum lub sijhawm ua pa.

Ua raws li qhov kev pom no, dej ua li cas los ua qhov nruab nrab rau cov txheej txheem metabolic?

Cov dej luag ua ib nruab nrab rau cov cov txheej txheem metabolic ntawm cov hlwb (2 cov ntsiab lus siab tshaj): Diffusion- tso cai rau kev txav ntawm cov ntaub ntawv los ntawm cov tshuaj aqueous hauv cov concentration gradient. Osmosis-kev txav ntawm dej nyob rau ntawm daim tawv nqaij vim dej muaj peev xwm sib txawv (down gradient)

Cov tshuaj twg yog qhov tseem ceeb li kev thauj mus los?

Dej yog heev tseem ceeb thauj nruab nrab rau cov kab mob uas muaj sia nyob vim nws cov khoom hnyav thiab vim tias nws tseem muaj cov kua dej ntau dhau ntawm qhov kub thiab txias.
