Not all phrases will be used. Thus, over time, the net movement of molecules will be out of the more concentrated area and into the less concentrated one, until the concentrations become equal (at which point, its equally likely for a molecule to move in either direction). Scheme facilitated diffusion in cell membrane, https://academic.oup.com/toxsci/article/80/1/54/1674897.

Image of a channel protein, which forms a tunnel allowing a specific molecule to cross the membrane (down its concentration gradient). instant, it may be moving in the opposite direction. The image below shows a potassium channel and its nonpolar and polar components. Cells require a constant exchange of solutes (ions and small molecules) with the outside of the cell. If you have, youve probably noticed that its carefully designed to let some things in (such as passengers with tickets) and to keep others out (such as weapons, explosives, and bottled water).
