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.
