A fake \"cell\" (a selectively permeable membrane enclosing an aqueous solution)

Question

A fake "cell" (a selectively permeable membrane enclosing an aqueous solution) is in a beaker as shown below. The membrane is permeable to glucose and fructose (monosaccharides) but not to sucrose (a disaccharide). Use arrows to show the net movements of solute into/out of the cell 2. Is the solution outside the cell hypertonic, isotonic, or hypotonic? Will osmosis occur? Which direction? What will happen to the fake cell? Eventually, will the two solutions (inside and outside the cell) have the same concentrations?

Explanation / Answer

1.Glucose has high conc. inside the cell hence it will move out.Fructose will move in as there is high conc. of fructose outside than inside.Sucrose will not move inspite of its concentration difference on both the sides as the cell membrane is impermeable to it.

2.Hypotonic solution.

3.Osmosis will occur from hypertonic soln. to hypotonic soln. i.e. from inside to outside.

4.The movement of glucose will take place from inside to outside till the equillibrum is attained i.e when conc, of glucoses becomes equal on both the sides.Also fructose will move inside till the conc. of fructose becomes equal on both the sides.

5.Yes this is called equillibrium.
