11. Which of the following would indicate that facilitated diffusion was taking place? A) A substance was moving from a region of low concentration into a region of higher concentration. B) Substances were moving against the diffusion gradient. C) A substance was slowing as it moved down its concentration gradient. D) ATP was being rapidly consumed as the substance moved. E) A substance was diffusing much faster than the physical condition indicated it should.

Osmosis

In simple words, osmosis is the slow, gradual movement of a liquid through a membrane. But there are nuances to this process. For instance, there has to be an imbalance in the distribution of solute in the liquid on either side of the membrane, which has to be semipermeable. The liquid in the region with a lower solute concentration moves to the region with a higher concentration, thereby displacing the solution in the process. The objective is to equalize the concentration of molecules on both sides of the membrane; the displacement of liquid can be viewed as a byproduct of this equalization. Since there is no energy required to carry osmosis, it is considered a passive process.
