Concept explainers

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.

Action potentials would be prolonged and the resting potential would be depolarised. Action potentials would be prolonged but the resting potential would remain the same. Neither resting potential nor action potentials would be affected because the concentration of X is less than the IC50 value. The resting membrane potential would depolarise but there would be no effect on action potentials.
