Question

Quizplus · Accepted Answer

Insulin is secreted by pancreatic beta cells and lowers blood glucose levels by promoting glucose uptake and storage. Glucagon, secreted by alpha cells, stimulates glycogen breakdown in the liver to increase blood glucose. It also promotes the use of fats and amino acids for energy. Insulin facilitates the synthesis of fats and proteins. Both hormones are regulated by negative feedback, but they are antagonists, not synergists.
