Answer:
a. Glucagon is released by the beta cells of the pancreatic islets of Langerhans.
Explanation:
When the body is fasting, the pancreas releases glucagon so that your body can produce glucose. Glucagon is a protein hormone made and secreted by alpha cells from pancreatic islets (or islets of Langerhans).
The islets of Langerhans are a special group of cells in the pancreas that produce not only glucagon, but also insulin. These substances act as important regulators of sugar metabolism.
