Study Notes

Insulin

Lowers blood glucose levels
Released when blood glucose rises above 110 mg/dl
Forces liver and muscles to take up glucose from bloodstream
Forces liver to make glycogen by linking glucose molecules together

Glucagon

Raises blood glucose
Released when blood glucose falls below 70 mg/dl
Forces liver to break down glycogen into glucose and release it into the bloodstream

Insulin

Lowers blood glucose levels
Released when blood glucose rises above 110 mg/dl

Forces liver to make glycogen by linking glucose molecules together

Glucagon

Raises blood glucose
Released when blood glucose falls below 70 mg/dl
Forces liver to break down glycogen into glucose and release it into the bloodstream
