1. concentration gradient - a gradient in concentration of a solute as a function of distance through a solution; "the movement of a solute down its concentration gradient is called diffusion". gradient - a graded change in the magnitude of some physical quantity or dimension. A difference in concentration of molecules in physical space is called a concentration gradient. An easy to understand example from everyday life is the application and subsequent fading of perfume or aftershave scent.

They have a rich blood supply to keep a concentration gradient. 2. These proteins use ATP hydrolysis to pump materials against their concentration gradients.

If we picture each individual molecule as a little blue dot, a constant concentration of molecules (no gradient) would look like the picture below: 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. 2018-05-08 · 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).
