Tus solute concentration yog siab dua nyob rau hauv lub cell. Yuav ua li cas yog qhov concentration gradient ntawm dej muaj feem xyuam rau osmotic siab ? qhov loj dua concentration ntawm dej hla ib daim nyias nyias, qhov ntau dua osmotic siab . Osmosis tau muab cais ua ib rooj plaub tshwj xeeb ntawm hom kev thauj mus los ntawm daim nyias nyias?

Yog li, qhov concentration gradient cuam tshuam li cas osmosis?

Concentration gradient - Lub zog ntawm osmosis yog cuam tshuam los ntawm concentration gradient ; qis tus concentration ntawm cov kuab tshuaj nyob rau hauv ib qho hnyav, qhov nrawm dua osmosis yuav tshwm sim hauv cov kuab tshuaj ntawd. Dej thiab Osmosis - Mus rau qhov txuas no thiab pom cov dej molecules txav mus hla ib daim nyias nyias nyias.

Ib yam li ntawd, puas muaj kev sib raug zoo ntawm kev ua dej thiab osmotic siab? Yog tus nto tsim muaj zog hydrogen bonds rau tus interfacial dej , tiam no dej yuav muaj qis dua dej kev ua si tshaj tus loj. Raws li tau piav nyob rau lwm qhov, qhov no ua rau tus nyiam ntawm sab nraud dej txav mus rau sab hauv thiab yog li ua rau nce osmotic siab.

Tsis tas li ntawd, lub siab osmotic cuam tshuam li cas rau qhov concentration ntawm cov kuab tshuaj hauv cov tshuaj?

Cov osmotic siab ntawm a daws yog cov siab Qhov sib txawv xav tau los nres qhov ntws ntawm cov kuab tshuaj hla lub semipermeable membrane. Cov osmotic siab ntawm a daws yog proportional rau molar concentration ntawm daws particle hauv daws . MM yog lub molar loj ntawm lub daws.

Puas yog osmotic siab nce nrog solute concentration?

Cov osmotic siab tsav cov dej hla ib qho impermeable barrier nce nrog qhov sib txawv hauv solute concentrations ntawm ob sab ntawm lub barrier. Osmotic siab nyob ntawm tus naj npawb ntawm daws particles, tsis nyob rau hauv lawv muaj pes tsawg leeg.
