Publisher Summary This chapter discusses the anaerobic glycolysis of alligators. Resting oxidative energy in a 700 kg alligator is only a few watts, an amount insufficient for locomotion on land. Very little energy is required for even such a large animal to swim slowly, and it is probable that the amount is enough for that purpose. At the maximum oxidative energy production rate, this large animal could probably develop as much as 60 W for a brief period of mechanical work. During the rapid synthesis of liver and muscle glycogen glucose ingestion, some of the glucose is oxidized to CO2 and water, but the amount lost by this route is not great. As no trace of excess glucose is ever present in the blood after 90 min or so, disappearance of that great amount of glucose could not have been the result of complete catabolism.
