What is glucagon’s major role in the body?
A
to raise blood sugar
B
to lower blood sugar
C
to receive signals from the pituitary
Explanation: 

Detailed explanation-1: -Glucagon is a glucoregulatory peptide hormone that counteracts the actions of insulin by stimulating hepatic glucose production and thereby increases blood glucose levels.

Detailed explanation-2: -When blood glucose levels fall too low (low blood glucose), the pancreas pumps out more glucagon. This hormone helps blood glucose rise back up in multiple ways: It causes the liver to convert stored glucose into a usable form and then release it into the bloodstream. (A process called glycogenolysis.)

Detailed explanation-3: -Glucagon triggers your liver to convert stored glucose (glycogen) into a usable form and then release it into your bloodstream. This process is called glycogenolysis. Glucagon can also prevent your liver from taking in and storing glucose so that more glucose stays in your blood.

Detailed explanation-4: -The role of glucagon in the body Stimulating the liver to break down glycogen to be released into the blood as glucose. Activating gluconeogenesis, the conversion of amino acids into glucose. Breaking down stored fat (triglycerides) into fatty acids for use as fuel by cells.

Detailed explanation-5: -It turns out that the -cells in type 2 diabetes become resistant to insulin, much like liver, fat and muscle. The result is that glucagon release is no longer inhibited during the mealtime rise in blood glucose, and this leads to the elevated levels of the hormone in type 2 diabetes.
