Which of the following are correct?A) Catecholamines stimulate glycogenolysis.B) Glucocorticoids stimulate proteolysis.C) Glucagon stimulates gluconeogenesis.D) Insulin stimulates glycogenesis.

Catecholamines stimulate the breakdown of glycogen (glycogenolysis).Glucocorticoids stimulate gluconeogenesis, lipolysis and proteolysis.Glucagon stimulates the process of gluconeogenesis which also contributes to hyperglycemia. Insulin stimulates conversion of glucose to glycogen (glycogenesis) in the target cells.
