Electron transfer (ET) occurs when an electron moves from an atom or a chemical species (e.g. a molecule) to another atom or chemical species. ET is a mechanistic description of the thermodynamic concept of redox, wherein the oxidation states of both reaction partners change. Numerous biological processes involve ET reactions. These processes incl...
