A chemical reaction in which an electron is transferred from one molecule to another. The electron-donating molecule is the reducing agent or reductant; the electron-accepting molecule is the oxidizing agent or oxidant. Reducing and oxidizing agents function as conjugate reductant-oxidant pairs or redox pairs (Lehninger, Principles of Biochemistry, 1982, p471).

Inorganic salts of the hypothetical acid ferrocyanic acid (H4Fe(CN)6).

An allotropic form of carbon that is used in pencils, as a lubricant, and in matches and explosives. It is obtained by mining and its dust can cause lung irritation.

The study of chemical changes resulting from electrical action and electrical activity resulting from chemical changes.

The facilitation of a chemical reaction by material (catalyst) that is not consumed by the reaction.

The rate dynamics in chemical or physical systems.

The process by which ELECTRONS are transported from a reduced substrate to molecular OXYGEN. (From Bennington, Saunders Dictionary and Encyclopedia of Laboratory Medicine and Technology, 1984, p270)
