When your muscles can't get enough oxygen during a short burst of exercise, they start to make use of a pathway called lactic acid fermentation, which generates a small three-carbon compound called lactic acid or lactate as a byproduct of glucose breakdown.
In humans, aerobic conditions produce pyruvate and anaerobic conditions produce lactate. In aerobic conditions, the process converts one molecule of glucose into two molecules of pyruvate (pyruvic acid), generating energy in the form of two net molecules of ATP. Four molecules of ATP per glucose are actually produced, however, two are consumed as part of the preparatory phase.
