CARBOHYDRATE CATABOLISM Carbohydrates are the primary source of energy for living organisms, although lipids and  proteins can also be used when carbohydrates are not available. Glucose is the fuel of choice, so  carbohydrate metabolism is usually studied as glucose metabolism.  Energy is produced from glucose in 2 main ways: 1. Cellular respiration 2. Fermentation Both processes begin with a series of ten reactions known as glycolysis or the Embden-Meyerhof  pathway. Each of these reactions requires its own specific enzyme, and none of the reactions use  oxygen (anaerobic).  In glycolysis, one 6-carbon molecule of glucose is converted to 2 3-carbon molecules of pyruvic  acid. As the reactions proceed, there are 2 that require the input of ATP. A total of 4 molecules of
