In general, the net movement of small, uncharged atoms and molecules through the membrane of a cell will occur until
A) the concentration of a solute is equal on both sides of the membrane.
B) all those atoms or molecules are on the same side of the membrane.
C) the cell grows so large that it can't hold any more material.
D) the cell shrinks to the point that it can't function properly.

Question

Quizplus · Accepted Answer

The net movement (diffusion) of small, uncharged atoms and molecules occurs from an area of high concentration to an area of low concentration until equilibrium is reached, meaning the concentration is equal on both sides of the membrane. Once this equilibrium is established, there is no further net movement of the molecules or atoms. Therefore, choice A is the correct answer. Choices B, C, and D are not accurate because they do not describe the principles of diffusion or the behavior of molecules and atoms in a system.
