When the body's blood glucose level rises, the pancreas secretes insulin and, as a result, the blood glucose level declines. when the blood glucose level is low, the pancreas secretes glucagon and, as a result, the blood glucose level rises. such regulation of the blood glucose level is the result of when the body's blood glucose level rises, the pancreas secretes insulin and, as a result, the blood glucose level declines. when the blood glucose level is low, the pancreas secretes glucagon and, as a result, the blood glucose level rises. such regulation of the blood glucose level is the result of protein-protein interactions positive feedback negative feedback catalytic feedback
