Metabolic Differences between Muscle and Liver in a “Fight or Flight” Situation. During a “fight or flight” situation, the release of epinephrine promotes glycogen breakdown in the liver, heart, and skeletal muscle. The end product of glycogen breakdown in the liver is glucose; the end product in skeletal muscle is pyruvate. (a) What is the reason for the different products of glycogen breakdown in the two tissues? (b) What is the advantage to an organism that must fight or flee of these specific glycogen breakdown routes?
