Question 8 (1 point) Page Which hormone is secreted by the pancreas and opposes the actions of insulin a) ADH b) ACTH c) thyroxine d) glucagon

The correct answer is **(d) glucagon**.<br /><br />Glucagon is a hormone produced by alpha cells in the pancreas. Its primary function is to increase blood glucose levels when they fall too low. It does this by stimulating the liver to break down stored glycogen (glycogenolysis) and to produce glucose from other sources (gluconeogenesis). This action directly opposes the effect of insulin, which lowers blood glucose levels.<br />
