- BStimulation of glycogenolysis
- CStimulation of gluconeogenesis
- DAll of the above
Correct answer
D. All of the above
Step-by-step solution
Glucagon is a peptide hormone, and plays an important role in maintaining the normal blood glucose levels. Glucagon acts mainly on the liver cells (hepatocytes) and stimulates glycogenolysis resulting in an increased blood sugar (hyperglycemia). In addition, this hormone stimulates the process of gluconeogenesis which also contributes to hyperglycemia. Glucagon reduces the cellular glucose uptake and utilisation. Thus, glucagon is a hyperglycemic hormone.Prolonged hyperglycemia leads to a complex disorder called di
