Chemiosmosis is a type of facilitated diffusion that takes place over the plasma membrane of a cell. Chemiosmosis is based on the concentration of molecules and electrically charged atoms or ions. Not only does diffusion work to make the concentration equal on both sides of the membrane, but also to equalize charge. The molecules move from an area from a high concentration to a low concentration. If there are more positive charged atoms outside the cell than inside the cell, they will want to move down their electrical gradient inside the cell. “Through a series of protein pumps in the electron transport chain, hydrogen ions are pumped across the membrane creating a chemiosmotic gradient.”(“How Do Mitochondria Use Chemiosmotic Gradients”). Basically, the chemiosmotic gradient drives the electron transport chain. The energy used from proton diffusion transforms ADP into
