6 a chemical gradient occurs when more of one molecule is on one side of a membrane, and more of another molecule is on the opposing side. An electrical gradient occurs when more positive or negative ions are on either side of a cell membrane potential, or voltage difference.
7 The combination of a chemical and electrical gradient can result in an electrochemical gradient that drives the movement of ions and molecules across a membrane.
8 an electrochemical membrane can have opposing components gradient.
