ox·i·da·tion-re·duc·tion

(ok'si-dā'shŭn-rē-dŭk'shŭn),
Any chemical oxidation or reduction reaction, which must, in toto, comprise both oxidation and reduction; the basis for calling all oxidative enzymes (formerly oxidases) oxidoreductases. Often shortened to "redox."

oxidation-reduction reaction

a chemical change in which electrons are removed (oxidation) from an atom, ion, or molecule, accompanied by a simultaneous transfer of electrons (reduction) to another. The reaction may also involve the transfer of electronegative atoms (e.g., oxygen) or atoms of low electronegativity (e.g., hydrogen or metal) from one molecule to another. Also called redox.

oxidation-reduction reaction

A chemical interaction in which one substance is oxidized and loses electrons, and thus is increased in positive valence, while another substance gains an equal number of electrons by being reduced and thus is decreased in positive valence. This is called a redox system or reaction.

oxidation-reduction reaction

a reversible chemical process in which electrons are transferred from one molecule to another.

Oxidation-reduction reactions in the biological system allow electrons and their accompanying protons to move from one molecule to another; every reduction must be accompanied by an oxidation.
Updated and expanded to cover the literature as of the end of 2005, it covers basic kinetic and mechanistic terminology and methodology, ligand substitution reactions, stereochemical change, reaction mechanism of organometallic systems, oxidation-reduction reactions, inorganic photochemistry, bioinorganic systems, and experimental methods.
NAD and NADH move hydrogen atoms back and forth between various oxidation-reduction reactions, helping to maintain balance between oxidation and reduction in the cell.
