Explanation: 

Detailed explanation-1: -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: -Glucagon is released to stop blood sugar levels dropping too low (hypoglycaemia), while insulin is released to stop blood sugar levels rising too high (hyperglycaemia). It is one of the ‘’anti-insulin” hormones. It works in totally opposite way to insulin.

Detailed explanation-3: -’Alpha cells’ in the islets of Langerhans produce another important hormone, glucagon. This has the opposite effect to insulin, by helping release energy into the bloodstream from where it is stored, thus raising blood sugar levels.

Detailed explanation-4: -The main actions that insulin has are to allow glucose to enter cells to be used as energy and to maintain the amount of glucose found in the bloodstream within normal levels. The release of insulin is tightly regulated in healthy people in order to balance food intake and the metabolic needs of the body.

Detailed explanation-5: -Insulin reduces the body’s blood sugar levels and provides cells with glucose for energy by helping cells absorb glucose. When blood sugar levels are too low, the pancreas releases glucagon. Glucagon instructs the liver to release stored glucose, which causes the body’s blood sugar levels to rise.
