Glucagon excess may also be as important as insulin insufficiency of diabetes. Glucagon: Stimulates lipolysis. Stops the release of amylin. Increases somatostatin production. Decreases ghrelin levels.

Answer: Glucagon stimulates lipolysis and decrease ghrelin levels.

Explanation:

Glucagon is an hormone that is secreted in the pancrease which convert stored glycogen to glucose that is released in the blood. High blood glucose increase insulin levels. Too much of glucagon can cause diabetes. Glucagon stimulate lipolysis which provide fatty acids to tissues to be use as fuel. Glucagon decrease the ghrelin levels. Glucagon stimulates amylin secretion.
