Summary

Five hours of freezing exposure at -2.5 deg C produced organ-specific changes in adenylates and energy charge, glycolytic intermediates, fermentative end products, glucose, fructose-2,6-bisphosphate, and the activity of glycogen phosphorylase in seven organs of garter snakes. Significant cryoprotectant synthesis was lacking, but the liver showed an activation of glycogenolysis and a 4-fold increase in glucose during freezing. Oxygen-sensitive organs, heart and brain, accumulated lactate during freezing exposure.
