Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
All of the following is true of glucagon, EXCEPT
A
it signals the liver to release glycogen as glucose
B
it signals the liver to store glucose as glycogen
C
it is released when blood sugar levels are low
D
it is secreted by alpha cells
Explanation: 

Detailed explanation-1: -Glucagon’s role in the body is to prevent blood glucose levels dropping too low. To do this, it acts on the liver in several ways: It stimulates the conversion of stored glycogen (stored in the liver) to glucose, which can be released into the bloodstream. This process is called glycogenolysis.

Detailed explanation-2: -Answer: B) Stimulating the production of glucose from pyruvate in the liver.

Detailed explanation-3: -Glucagon is a primary regulator of hepatic glucose production (HGP) in vivo during fasting, exercise and hypoglycaemia. Glucagon also plays a role in limiting hepatic glucose uptake and producing the hyperglycaemic phenotype associated with insulin deficiency and insulin resistance.
