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
A) catalytic feedback.
B) positive feedback.
C) negative feedback.
D) bioinformatic regulation.
E) protein-protein interactions.

Question

The regulation of blood glucose level by the pancreas through insulin and glucagon secretion is an example of negative feedback. Negative feedback occurs when a physiological response reduces the initial stimulus, in this case, the secretion of insulin reduces the high blood glucose level while the secretion of glucagon raises the low blood glucose level.
