When Blood Glucose Levels Fall

Question

When blood glucose levels fall,
A) insulin is released.
B) glucagon is released.
C) peripheral cells take up more glucose.
D) protein synthesis increases.
E) calcitonin is secreted.

Accepted Answer

When blood glucose levels fall, the hormone glucagon is released by the pancreas to stimulate the liver to break down glycogen into glucose and release it into the bloodstream, raising glucose levels. Insulin is released when blood glucose levels rise to help move glucose into cells for energy or storage. Peripheral cells taking up more glucose and protein synthesis increasing are not direct responses to falling blood glucose levels. Calcitonin is not involved in glucose regulation.
