Several hours after your last meal,declining blood glucose levels stimulate release of the hormone ________,which stimulates glycogenolysis,lipolysis and fat mobilization,and gluconeogenesis.

Question

Quizplus · Accepted Answer

Glucagon is released when blood glucose levels decline after several hours of fasting. It stimulates the liver to break down glycogen into glucose (glycogenolysis), release fatty acids from adipose tissue (lipolysis), and convert amino acids into glucose (gluconeogenesis) to maintain blood glucose levels. Thyroxine, cortisol, and insulin can also affect carbohydrate and lipid metabolism, but they are not primarily responsible for the changes that occur during fasting.
