Agree with C. Cortisol promotes muscle glycogenolysis not liver. In fact in the liver it increases glycogen storage

Correct Answer C - correct answer

C) Glucagon and catecholamines such as epi- nephrine stimulate the mobilization of glycogen by triggering the cAMP cascade. Hormones that increase liver cell cAMP promote glycogen break- down, and hormones that decrease liver cell cAMP promote glycogen synthesis.

Cortisol, the main glucocorticoid, regulates the metabolism of proteins, fats, and carbohydrates. It acts on most organs catabolically. However, on the liver it has anabolic effects, increasing glycogen synthesis and accumulation in the liver.
