Question

Quizplus · 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, thereby raising blood glucose levels. Insulin is released when blood glucose levels are high to stimulate cells to take up glucose for energy or storage. Peripheral cells taking up more glucose and an increase in protein synthesis are not directly related to blood glucose levels falling. Therefore, the best choice is B, glucagon is released.
