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.
