What is Anaerobic Fermentation? (with pictures)

M. Walker Breweries use anaerobic fermentation to make beer. Anaerobic fermentation is a method cells use to extract energy from carbohydrates when oxygen or other electron acceptors are not available in the surrounding environment. This differentiates it from anaerobic respiration, which doesn’t use oxygen but does use electron-accepting molecules that come from outside of the cell.

Abstract - University of New Mexico

In an anaerobic environment, the yeast cells undergo fermentation. In fermentation, glucose enters glycolysis and produces reduced NADH +H+ and pyruvate molecules. In the next part pyruvate is converted to acetaldehyde and then to ethanol. This step oxidizes the NADH back to NAD+ so that it may be regenerated and reused in the glycolysis.
