Pancreatic hormones that lower and raise blood sugar.
Beta cells in islets release insulin; alpha cells release glucagon. They oppose each other, maintaining blood glucose. Insulin was discovered by Banting and Best in 1921.
Insulin lowers blood glucose; glucagon raises it. Both are peptide hormones. Type 1 diabetes involves insulin deficiency.
Key idea: the pair maintains a steady glucose level.
