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. Dej kuj pab tau ntau yam kab mob tswj metabolism thiab dissolves tebchaw nkag mus rau hauv los yog tawm ntawm lub cev.
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. Lub cohesion (stickiness) ntawm cov dej molecules txhais tau hais tias lub siab nyias nyias ntawm cov dej tuaj yeem txhawb nqa ua ntej nws tawg.

Vim li cas cov tshuaj tiv thaiv kev zom zaub mov hu ua hydrolysis cov tshuaj tiv thaiv?
Thaum lub sij hawm zom mov, piv txwv li, decompositionreactions zom cov zaub mov loj rau hauv cov me me los ntawm kev ntxiv cov dej molecules. Hom tshuaj no hu ua hydrolysis. Raws li dej absorbs heatenergy, qee lub zog yog siv los rhuav tshem hydrogenbonds
Cov tshuaj tiv thaiv zoo li cas thaum cov tshuaj nkag mus rau hauv cov hlab ntsha?
Cov tshuaj tiv thaiv 'systemic' tshwm sim thaum cov tshuaj nkag mus rau hauv cov hlab ntsha los ntawm daim tawv nqaij, qhov muag, qhov ncauj, lossis lub ntsws
Cov tshuaj tiv thaiv dab tsi yog qhov tshuaj tiv thaiv neutralization?
Neutralization yog ib hom tshuaj tiv thaiv nyob rau hauv uas muaj zog acid thiab muaj zog puag react nrog ib leeg los tsim dej thiab ntsev
Dab tsi yog tshuaj lom neeg cov tshuaj tiv thaiv thiab cov tshuaj tiv thaiv lub cev?
Qhov sib txawv ntawm cov tshuaj tiv thaiv lub cev thiab cov tshuaj tiv thaiv tshuaj yog muaj pes tsawg leeg. Hauv cov tshuaj tiv thaiv tshuaj, muaj kev hloov pauv ntawm cov tshuaj hauv nqe lus nug; nyob rau hauv ib qho kev hloov ntawm lub cev muaj qhov sib txawv ntawm qhov tsos, tsis hnov tsw, los yog cov duab yooj yim ntawm cov qauv ntawm cov teeb meem yam tsis muaj kev hloov pauv hauv cov ntsiab lus
Koj ua li cas sib npaug redox cov tshuaj tiv thaiv hauv acidic thiab nruab nrab nruab nrab?
Acid Conditions Solution. Kauj Ruam 1: Sib cais ib nrab cov lus teb. Kauj Ruam 2: Ntsuas cov ntsiab lus uas tsis yog O thiab H. Kauj Ruam 3: Ntxiv H2O kom sib npaug ntawm cov pa. Kauj Ruam 4: Sib npaug hydrogen los ntawm kev ntxiv protons (H +). Kauj Ruam 5: Ntsuas tus nqi ntawm txhua qhov sib npaug nrog electrons. Kauj Ruam 6: Ntsuas cov tshuaj tiv thaiv kom cov electrons sib npaug
