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.

The supernatant and pellet samples were then prepared for SDS-PAGE identically and run via normal SDS-PAGE procedures. In the figure, "s" means supernatant and "p" means pellet. The text or number after the dash represents a different condition. For example, s-1 and p-1 are the supernatant and pellet samples under condition 1.

Protein was measured and found to have a concentration of at 308.35 µg/ml Recall, mass = concentration * volume 10 µg = 308.35 µg/ml * V V = 0.01 mg/ 0.30835 mg/mL = 0.032430679 mL = 32.43067942 µL Note: cannot measure this amount; two dilutions required. Dilute by 1/40: measure 2.5 µl of protein at 0.30835 µg/µl and add it to 97.5 diluent to prepare a solution of protein at 7.71 mg/ml. This diluted sample will be used further. Mass = concentration * volume 10 µg = 7.71 mg/ml * V V = 0.01 mg/ 7.71 mg/ml = 1.3 µL Therefore, will measure 1.3 µl of protein at 7.71 mg/ml and add it to 28.7 µl of diluent.
