<span> When a cell membrane becomes energized due to electron transport reactions by the electron carriers embedded in it then this results in proton motive force (PMF). This way the cell becomes a tiny battery. </span><span>
The proton motive force (PMF) is driven by </span>the difference in charge across the plasma membrane with protons outside the membrane.
