WebFeb 11, 2015 · Molecules diffuse from areas of high concentration, to areas of low concentration, down a concentration gradient. The concentration gradient therefore represents the concept that, just as a ball rolls down a slope, during diffusion molecules move down the concentration gradient.

WebA specialized example of facilitated transport is water moving across the cell membrane of all cells, through protein channels known as aquaporins. Osmosis is the diffusion of water through a semipermeable membrane from where there is more relative water to where there is less relative water (down its water concentration gradient) (Figure 3.1.5).
