If a solute concentration gradient has been established across a membrane, the permeable solute will diffuse across the membrane:
Multiple Choice
so slowly that there will be no movement of these molecules, even though the membrane is permeable to them.
from the side with a lower concentration to the side with a higher concentration.
in both directions, but with no net movement in any particular direction.
from the side with a higher concentration to the side with a lower concentration.
