When blood glucose level rises, the pancreas secretes insulin, and as a result blood glucose level declines. When blood glucose level is low, the pancreas secretes glucagon, and as a result blood glucose level rises. Such regulation of blood glucose level is the result of
A)catalytic feedback.
B)positive feedback.
C)negative feedback.
D)bioinformatic regulation.
E)protein-protein interactions.

This is an example of negative feedback, where the body's response reduces the deviation from the desired set point. In this case, when blood glucose levels rise, insulin is secreted to decrease the levels, and when they fall, glucagon is secreted to increase them. This maintains a relatively stable blood glucose level.
