Hypoglycemia, or Low Levels of Glucose in the Blood of a Healthy

Question

Hypoglycemia, or low levels of glucose in the blood of a healthy human, is "corrected" by a(n)
A) increase in the secretion of insulin.
B) increase in the secretion of glucagon.
C) increase in the secretion of both insulin and glucagon.
D) decrease in the secretion of both insulin and glucagon.
E) increase in the secretion of thyroid hormones.

Accepted Answer

Glucagon is a hormone produced by the pancreas that works to raise the concentration of glucose in the bloodstream. When blood sugar levels are low (hypoglycemia), the secretion of glucagon increases to stimulate the liver to release stored glucose, thereby raising blood glucose levels. Insulin, on the other hand, lowers blood glucose levels and would not be increased in response to hypoglycemia.
