Major electron carrier of catabolism, in reduced form.

NADH serves within cells as an reducing agent/electron donor. NAD+ is the corresponding oxidized form.

Two NADH are produced by glycolysis, one in the course of pyruvate oxidation, and another three during the Krebs cycle. This NADH then either donates its electrons to an electron transport chain, regenerating NAD+, or instead is recycled back to NAD+ via fermentation pathways.
