Students have asked these similar questions
Assume that a beaker is divided in half by a membrane which is permeable to water only. A 0.45 M glucose solution is on one side of the membrane, and a 0.40 M NaCl solution is on the other side of the membrane. Indicate which direction would water move. Explain why the movement occurs in that direction.
part 1 Reaching osmotic balance across a semipermeable membrane for non-charged molecules depends on:
a.Relative solute concentration gradient across the membrane
b.Relative electrical gradient across the membrane
c.Relative solute concentration and electrical gradient across the membrane
part 2 The equilibrium of a charged molecule across a semipermeable membrane depends on:
a.Relative solute concentration gradient across the membrane
b.Relative electrical gradient across the membrane
c.Relative solute concentration and electrical gradient across the membrane
Would water molecules move faster when there is a high concentartion gradient or low concentartion gradient?
I think basically this question is asking if water molecules will move faster using passive transport or active transport? since it involves water molecules wouldn't it be passive transport since osmosis is a type of passive transport? I'm confused
