As electrons are passed down the chain, they move from a higher to a lower energy level, releasing energy. Some of the energy is used to pump H + ^+ + start superscript, plus, end superscript ions, moving them out of the matrix and into the intermembrane space. This pumping establishes an electrochemical ... WebIf an electron is floating around on its own, its kinetic energy can be very low.

WebCan positive charges move? If a positively charged object, like a proton, is in an electric field, it will be pushed by the field and move. On the other hand, in an atom, even though electrons and protons both experience a force toward each other, the electron moves a lot more because it is much, much lighter than the proton.
