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
D
None of the above
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: -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-3: -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-4: -Mini-dose glucagon will usually raise blood glucose 50 to 100 mg/dl (points) in 30 minutes without causing nausea.

Detailed explanation-5: -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.
