A concentration gradient occurs where the concentration of something changes over a certain distance. For example, a few drops of food dye in a glass of water diffuse along the concentration gradient, from where the dye exists in its highest concentration (for instance, the brightest blue or red) to where it occurs in its lowest concentration (the water is still clear). A concentration gradient occurs when a solute is more concentrated in one area than another. “Concentration” refers to how much of a solute there is compared to solvent. A corner of a water tank that has just had salt dumped into it, for example would have a much higher concentration of salt than the opposite end of the tank, where no salt has reached. The concentration gradient is one component of the electrochemical gradient (the chemical part) that determines the direction an ion will move when a transmembrane ion channel is opened. The other component is the electrical gradient is determined by the number and quantity of electrical charges present across the membrane.
