Oxidation And reduction

Oxidation and reduction

Paired chemical changes in which electrons move from one molecule to another.

Overview

EXPLORE BY LEVEL

In a redox reaction, one molecule gives up electrons and another accepts them. Cells use these transfers to move energy and to change molecules.

Biological redox reactions are enzyme-catalyzed and governed by substrate/cofactor potentials, compartmental redox state, and reaction coupling. NADH and NADPH pools are regulated for distinct, though interacting, metabolic roles.
