Question

glucagon effects
what is the main effect of glucagon?
regulate sodium and potassium ion levels
regulate blood pressure
raise blood glucose levels
lower blood glucose levels

Explanation:

Glucagon is a hormone produced by the pancreas. When blood glucose levels are low, the pancreas releases glucagon. Glucagon acts on the liver. It promotes glycogenolysis (the breakdown of glycogen into glucose) and gluconeogenesis (the synthesis of glucose from non - carbohydrate sources like amino acids). These processes increase the amount of glucose in the bloodstream.
Regulating sodium and potassium ion levels is mainly the function of hormones like aldosterone. Regulating blood pressure is a complex process involving multiple systems and hormones such as renin - angiotensin - aldosterone system, but not glucagon. Lowering blood glucose levels is the function of insulin.

Answer:

Raise blood glucose levels
