Any of various molecules, such as cytochromes and quinonoid compounds, that accept one or two electrons from one molecule and donate them to another in the process of electron transport, resulting in the release of energy that is used to produce ATP.
electron carrierA compound, such as a coenzyme, capable of taking up electrons from a molecule and transferring them to another, thereby undergoing reversible reduction and oxidation.
any of the negatively charged particles arranged in orbits around the nucleus of an atom and determining all of the atom's physical and chemical properties except mass and radioactivity. Electrons flowing in a conductor constitute an electric current; when ejected from a radioactive substance, they constitute the beta particles.
the stream of electrons that flows from the anode to the cathode in the x-ray tube and then interacts with the tungsten target to produce x-rays.
a molecule associated with membrane-bound proteins that accepts and transfers electrons.
photographic images of electron microscopic fields.
see electron microscope.
