How many ATP's could theoretically be produced when a granule of glycogen is hydrolyzed to glucose subunits that then enter glycolysis and respiration? B. Glycogen metabolism is regulated by insulin and glucagon. Both of these hormones are produced by the pancreas and act as signals that interact with a transmembrane receptor on target cells. Intracellular events involve protein kinase A that activates or inactivates enzymes involved in glycogen synthesis or degradation. Briefly describe what protein kinase A does to these proteins.
