Definitions:

Exergonic

Describes a reaction that ends with a net release of free energy.

Oxidized

A chemical process where a molecule, atom, or ion loses electrons, often leading to its reaction with oxygen.

Reduced

Often refers to the gain of electrons or decrease in oxidation state by a molecule, atom, or ion.

Ionized

The state of an atom or molecule when it has lost or gained one or more electrons, thus carrying a charge.
