So on top of these molecules moving to the right side as a result of an electric gradient, because there is an attraction between the positive and negative, these C molecules will also move to the right side because they will move from a high C concentration to a low C concentration. So this concept, this scenario actually incorporates both the concentration gradient and our electrical gradient. So at the end, we have an even amount of molecules on both sides, and the charges are also in equilibrium. We have no net charge here and no net charge here. And this is the electrochemical gradient. So basically, one of the purposes of our cell membrane is to create an electrochemical gradient.
