Is the secretion of glucagon controlled by a negative or a positive feedback loop?

Solution

The secretion of glucagon controlled by a negative feedback loop.The action of glucagon is to raise the blood sugar levels.When the blood sugar levels in the blood is too high, the pancreas prevents the secretion of glucagon and starts to release insulin to counteract the effect of glucagon and maintain a balance of the blood sugar.
