III. Oxidation- Reduction Reactions

A. Characteristics of Redox RXNs B.

OILRIG

Oxidation is Losing, Reduction is Gaining

Reducing agent

e- doner, loses an H

Oxidized in a redox reaction

Oxidizing Agent

= e- acceptor, gains an H

Reduced in redox reaction, electron carriers

E- alone difficult to remove from covalent compound

Redox Summary

Metabolism involves moving e0

Coupled reactions that involve the gain and loss of e-

E acceptor compounds like NAD+ are used to store and use E during metabolism
