In glycolysis, glucose (a six carbon sugar) is split into two molecules of a three-carbon sugar. Glycolysis yields two molecules of ATP (free energy containing molecule), two molecules of pyruvic acid and two high energy electron carrying molecules of NADH. Glycolysis can occur with or without oxygen. In the presence of oxygen, glycolysis is the first stage of cellular respiration. Without oxygen, glycolysis allows cells to make small amounts of ATP. This process is called fermentation.
Anaerobic means without oxygen, and respiration refers to the processes in a cell that convert biochemical energy, such as that found in glucose, into usable energy in the form of ATP. Waste products like carbon dioxide are also produced during this process. The fermentation process in anaerobic respiration is roughly 5 percent as effective as what cells can do when they have access to oxygen. An aerobic cycle may produce between 36 and 38 ATP molecules, while anaerobic respiration only creates 2 ATP molecules.
