What is the role of glucagon in the body? What is the target organ? What does it cause to happen?

Answer 1

Glucagon is a hormone that plays a key role in regulating blood sugar levels in the body. Its main role is to raise blood sugar levels by stimulating the liver to break down glycogen (stored glucose) and release it into the bloodstream.

The target organ of glucagon is the liver. When released, glucagon binds to receptors on liver cells and activates enzymes that break down glycogen into glucose, which is then released into the bloodstream.

Overall, glucagon helps to maintain stable blood sugar levels by increasing glucose production and release when levels are too low, such as during fasting or between meals.
