Question

Quizplus · Accepted Answer

Insulin and glucagon are both hormones secreted by the pancreas and are involved in the regulation of blood glucose levels. Insulin is secreted in response to high blood glucose levels and lowers blood glucose levels by promoting the uptake of glucose by cells and the storage of excess glucose as glycogen. Glucagon, on the other hand, is secreted in response to low blood glucose levels and promotes the release of glucose into the bloodstream by stimulating the breakdown of glycogen in the liver.
