Question

Quizplus · Accepted Answer

Insulin is secreted by pancreatic beta cells and lowers blood glucose levels by facilitating cellular uptake of glucose. Glucagon is secreted by pancreatic alpha cells and stimulates the liver to convert glycogen to glucose, increasing blood glucose levels. Glucagon also promotes the use of fats and amino acids for energy. Insulin promotes the synthesis of fats and proteins from fatty acids and amino acids. Both hormones are regulated by negative feedback mechanisms, but they are considered antagonists, not synergists.
