How is fermentation different than glycolysis?

Fermentation is a metabolic process that converts sugar (primarily glucose, fructose and sucrose) to acids, gases or alcohol. However, the sole energy extraction pathway is glycolysis plus one or two extra reactions. It is basically the Regeneration of NAD.

Glycolysis is defined as an enzymatic breakdown of carbohydrates (as glucose) by way of phosphate derivatives with the production of pyruvic or lactic acid and energy stored in high-energy phosphate bonds of ATP.

Fermentation: Fermentation is a metabolic process that converts sugar into acids, gases or alcohol.

Glycolysis: Glycolysis is an enzymatic breakdown of carbohydrates.
