Qhov tseem ceeb sib txawv - Isotonic vs Hypertonic
Nws yog ib qho tseem ceeb kom nkag siab txog lub tswv yim ntawm Tonicity ua ntej txheeb xyuas qhov sib txawv ntawm isotonic thiab hypertonic. Yog li ntawd, cia peb xub piav luv luv lub tswvyim ntawm tonicity thiab nws qhov tseem ceeb. Tonicity yog qhov sib txawv hauv cov dej concentration ntawm ob txoj kev daws teeb meem los ntawm semipermeable membrane. Nws kuj tseem tuaj yeem piav qhia raws li tus txheeb ze dej concentration ntawm cov kev daws teeb meem uas txiav txim siab qhov kev taw qhia thiab qhov sib txawv ntawm cov dej kom txog thaum nws ua tiav qhov sib npaug ntawm ob sab ntawm daim nyias nyias. Los ntawm kev txheeb xyuas qhov tonicity ntawm cov kev daws teeb meem, peb tuaj yeem txiav txim siab seb cov dej yuav ua li cas. Qhov tshwm sim no feem ntau yog siv thaum qhia txog cov lus teb ntawm cov hlwb immersed nyob rau hauv ib qho kev daws sab nraud. Muaj peb qhov kev faib tawm ntawm tonicity uas ib qho tshuaj tuaj yeem muaj txheeb ze rau lwm tus. Lawv yog hypertonic, hypotonic, thiab isotonic. Qhov sib txawv tseem ceeb ntawm Isotonic thiab Hypertonic yog tias cov tshuaj hypertonic muaj cov kuab tshuaj ntau dua li cov kuab tshuaj thaum cov kuab tshuaj thiab cov kuab tshuaj sib npaug sib npaug hauv cov tshuaj isotonic. Txawm li cas los xij, nco txog lub ntsiab lus ntawm hypertonic thiab isotonic cov kev daws teeb meem tsis yog qhov tseem ceeb yog tias peb tuaj yeem nkag siab qhov txawv ntawm isotonic thiab hypertonic daws.
YHypertonic yog dab tsi?
Hyper yog lwm lo lus rau saum toj lossis ntau dhau. Hypertonic kev daws teeb meem yuav muaj ntau dua cov kua qaub (glucose lossis ntsev) dua li ntawm tes. Solutes yog cov ntsiab lus uas yaj hauv cov kuab tshuaj, yog li tsim cov tshuaj. Hauv cov tshuaj hypertonic, qhov concentration ntawm cov kuab tshuaj yog ntau dua sab nraud ntawm tes tshaj li hauv nws. Thaum ib lub xovtooj nkag mus rau hauv cov tshuaj hypertonic yuav muaj kev hloov pauv osmotic thiab cov dej molecules yuav ntws tawm ntawm lub xovtooj mus rau qhov sib npaug ntawm cov kuab tshuaj thiab yuav muaj shrinkage nyob rau hauv qhov loj ntawm lub cell.
Isotonic yog dab tsi?
Iso yog lwm lo lus sib npaug thiab tonic yog rau tonicity ntawm kev daws. Isotonic cov kev daws teeb meem yuav muaj qhov sib xws ntawm cov kuab tshuaj dua li cov tshuaj uas nws tau muab piv rau. Nyob rau hauv ib qho kev daws teeb meem isotonic, qhov concentration ntawm cov kuab tshuaj yog tib yam ob sab hauv thiab sab nraud ntawm tes tsim kom muaj kev sib npaug hauv ib puag ncig ntawm lub koom haum cellular. Thaum ib lub xovtooj nkag mus rau hauv cov tshuaj isotonic, yuav tsis muaj kev hloov osmotic thiab dej molecules diffuse los ntawm cov cell membrane nyob rau hauv ob qho tib si cov lus qhia kom sib npaug cov concentration ntawm solutes. Cov txheej txheem no yuav tsis tsim o lossis shrinking ntawm tes.
Qhov txawv ntawm Isotonic thiab Hypertonic yog dab tsi?
Qhov sib txawv ntawm hypertonic thiab isotonic tuaj yeem muab faib ua pawg hauv qab no.
Txhais ntawm Isotonic thiab Hypertonic
Hypertonic: "hyper" yog lub npe hu ua saum toj no lossis ntau dhau + "tonic" yog lub npe hu ua ib yam dab tsi raws txoj kab ntawm kev daws teeb meem. Yog li, hypertonic qhia kom muaj zog tonicity ntawm cov tshuaj.
Isotonic: "iso" paub zoo ib yam + "tonic" yog lub npe hu ua ib yam dab tsi raws cov kab ntawm kev daws teeb meem. Yog li, isotonic qhia zoo li tonicity ntawm cov tshuaj.
yam ntxwv ntawm Isotonic thiab Hypertonic
Kev sib xyaw ntawm cov kuab tshuaj thiab tshuaj
Hypertonic: Cov tshuaj muaj cov kuab tshuaj ntau dua li cov kuab tshuaj.
Isotonic: Solute thiab hnyav hauv cov tshuaj tau muab faib ua qhov sib npaug.
Examples
Hypertonic: Cov dej huv huv, vim tias tsis muaj / tsawg dua cov kua dej yog yaj hauv cov dej huv huv, thiab nws cov concentration tsawg heev piv rau ib puag ncig ntawm tes.
Isotonic: Cov kua ntsev yog ib qho isotonic rau tib neeg cov ntshav ntshav
Cells teb hauv cov tshuaj hypertonic thiab isotonic (Saib daim duab 1)
Hypertonic: Thaum lub cell lom nyob rau hauv ib puag ncig hypertonic, dej ntws hla cov cell membrane tawm ntawm lub xovtooj, txhawm rau sib npaug cov concentration ntawm cov kua hauv ob lub xovtooj ntawm tes thiab ib puag ncig ib puag ncig ntawm tes. Raws li qhov tshwm sim, lub xovtooj ntawm tes yuav txo qis thaum dej tawm hauv lub cell kom txo cov concentration ntau dua ntawm cov kua dej nyob hauv ib puag ncig sab nraud.
Isotonic: Thaum lub xov tooj ntawm tes nyob rau hauv cov tshuaj isotonic, nws yuav tsis tsim o lossis shrinking ntawm tes.
Dej concentration gradient
Hypertonic: Dej concentration gradient tuaj yeem pom los ntawm sab hauv ntawm tes mus rau cov tshuaj hypertonic
Isotonic: Dej concentration gradient tsis muaj nyob
Solute concentration gradient
Hypertonic: Solute concentration gradient pom los ntawm cov tshuaj hypertonic mus rau sab hauv ntawm tes
Isotonic: Solute concentration gradient tsis muaj nyob.
Osmotic hloov
Hypertonic: osmotic hloov pauv tshwm sim.
Isotonic: osmotic hloov tsis muaj nyob
Kev txav dej
Hypertonic: Cov dej molecules txav los yog nthuav tawm sai sai ntawm sab hauv ntawm tes mus rau sab nrauv cov lus qhia, thiab yog li lub cell yuav poob dej.
Isotonic: Cov dej molecules txav los yog sib txawv ntawm ob qho tib si, thiab tus nqi ntawm cov dej ntws zoo sib xws hauv txhua qhov kev taw qhia. Yog li cell yuav tau los yog poob dej.
Sports Drinks
Isotonic: Ib qho dej haus isotonic suav nrog cov ntsiab lus zoo sib xws ntawm ntsev, qab zib carbohydrate thiab electrolytes ib yam li hauv tib neeg lub cev. Isotonic kev ua kis las haus dej haus feem ntau yog nyiam los ntawm qhov ncauj ua kom dej. Nws feem ntau muaj 4-8g carbohydrate ib 100 ml.
Hypertonic: Hypertonic haus muaj ntau dua ntsev, qab zib carbohydrate thiab electrolytes ib yam li hauv tib neeg lub cev. Nws feem ntau muaj kwv yees li 8 g ntawm carbohydrate ib 100 ml. Ib qho kev daws teeb meem hypertonic kuj tseem siv rau hauv osmotherapy txhawm rau tswj cov ntshav hauv hlwb. Hypertonic kis las dej haus yog qhov zoo tagnrho rau cov neeg uas xav tau lub zog siab heev.
Nyob rau hauv xaus, muaj peb hom kev daws teeb meem uas yog raws li cov kuab tshuaj concentration thiab lawv yog isotonic, hypotonic, thiab hypertonic. Qhov concentration ntawm solutes yog tib yam ob sab hauv thiab sab nraud ntawm tes hauv cov tshuaj isotonic. Lub concentration ntawm solutes yog ntau dua nyob rau hauv lub cell tshaj li sab nraud ib puag ncig nyob rau hauv ib tug hypotonic tov whereas cov tshuaj hypertonic yog ib qho uas cov concentration ntawm solutes yog ntau dua sab nraum ib puag ncig tshaj nyob rau hauv lub cell.
