Introduction:

There are some pathways in which energy is released in the absence of oxygen. These pathways are known as anaerobic energy pathways. In anaerobic respiration, pyruvate released from glycolysis either produces ethanol or lactic acid. If it results into ethanol as a product, it is known as alcoholic fermentation. This process is used commercially to make alcoholic beverages, beers, bread, and other bakery products.
