Concentration gradient concept
When we speak of a concentration gradient, we refer to the difference in concentration that exists in a molecule between one region and another. In the case of cell membranes, it is the difference that exists in the attention of ions located on different sides of the membrane.
Easily understood, the concentration gradient is the difference in solute concentration between two solutions or media. It is best to have a practical example that allows you to visualize it better to understand this concept.
Concentration gradient example
The concentration gradient is the difference in concentration of an element in the same area or solution. A straightforward and easy-to-understand example is what we can obtain when we add a tablespoon of salt to a glass of water.
By pouring it without shaking the water, we will see how the highest salt concentration goes directly to the bottom of the glass, while only tiny particles of salt remain in the upper part of the glass. This critical difference in salt concentration between both glass areas is known as the concentration gradient.
Another concept closely linked to this is diffusion, which occurs when a net movement of particles occurs in favor of their concentration gradient. The particles move from where they are present in greater quantity to where they are in less amount. This happens, for example, when the salt molecules end up mixing in the water.
