WebGlycogen/glucose metabolism ( Fig. 151.1) Anaerobic glycolysis is the main metabolic pathway used in the setting of limited oxygen supply during exercise. It is used during high-intensity, sustained, isometric muscle activity.1 It is inefficient from an energetic standpoint and produces only two ATP molecules per glucose molecule, which is 19 ... WebThis results in the production of ATP and lots of lactic acid. After exercise, the liver and muscles need to convert the lactic acid back to pyruvic acid. In order to do that, a lot of the oxygen the body is now taking in does the conversion instead of being used elsewhere. This is known as “repaying the debt,” hence the term “oxygen debt.”
