Skip navigation concentration - the strength of a solution; number of molecules of a substance in a given volume In pharmacology , the term concentration refers to the strength of a pharmaceutical preparation. A solution, essentially, has two major components, the solvent (the dissolving component, e.g. the movement of a substance across a biological membrane against its concentration gradient, aided by specific transport proteins and requiring an input of energy (often as ATP) (5.8) Aquaporin a transport protein in the plasma membrane of some plant or animal cells that facilitates the diffusion of water across the membrane (osmosis) (5.6) A solvent is a substance that dissolves another substance by pulling the molecules apart through electrochemical interactions. The important thing to know is that concentration in biology is almost always referring to the amount of something in a liquid solution -- be it blood, water, an organic solvent in a test tube, etc.
