Question

Quizplus · Accepted Answer

Insulin and glucagon are both hormones secreted by the pancreas to regulate blood glucose levels. Insulin is secreted by beta cells when blood glucose levels are high, promoting glucose uptake into cells and lowering blood glucose levels. Glucagon is secreted by alpha cells when blood glucose levels are low, promoting glycogen breakdown and glucose release into the bloodstream, raising blood glucose levels.
