the conversion of glucose, by a series of ten enzyme-catalysed reactions, to lactic acid. Glycolysis takes place in the cytoplasm of cells and the first nine reactions (converting glucose to pyruvate) form the first stage of cellular respiration. The process involves the production of a small amount of energy (in the form of ATP), which is used for biochemical work. The final reaction of glycolysis (converting pyruvate to lactic acid) provides energy for short periods of time when oxygen consumption exceeds demand; for example, during bursts of intense muscular activity.
