Web'Glycolysis is a series of reactions in which six-carbon sugar is broken down to two molecules of the three-carbon pyvurate ion' (from Advanced Biology by John Murray). The process of glycolysis are common to both anaerobic and aerobic respiration. After glycolysis takes place, the product pyvurate enters the mitochondria. WebSummary.
