Which are true about glucagon? (2)
A
it is secreted by
B
it is secreted by
C
it causes an uptake of glucose into cells all over the body
D
it causes enzymes to convert glycogen and amino acids into glucose
Explanation: 

Detailed explanation-1: -Your body primarily stores glycogen in your liver and muscles. Glucagon is a hormone that triggers liver glycogen to convert back into glucose and to enter your bloodstream so that your body can use it for energy.

Detailed explanation-2: -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.) Glucagon also stops the liver from taking in and storing glucose, so more stays in the blood.

Detailed explanation-3: -Glucagon Promotes Break-Down of Amino Acids During prolonged fasting, glucagon stimulates formation of glucose from amino acids (via gluconeogenesis) by upregulating enzymes involved in the process.

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.
