What role does glucagon play during a severe hypoglycemic episode?

Glucagon plays a vital role during a severe hypoglycemic episode by raising blood sugar levels. When blood sugar levels drop significantly, glucagon is secreted from the alpha cells of the pancreas. Its main function is to stimulate the liver to convert glycogen, which is stored glucose, back into glucose and release it into the bloodstream. This process helps to rapidly increase blood glucose levels, counteracting the effects of hypoglycemia.

Understanding this mechanism is crucial for managing diabetic emergencies, as timely administration of glucagon can effectively alleviate severe hypoglycemic events and restore normal blood sugar levels. The other options do not accurately reflect the action of glucagon; rather, they describe functions related to insulin or digestion, which are unrelated to glucagon's primary role in glucose regulation.
