Question

Which is the best example of negative feedback at work?

A) an inhibiting hormone with twice the half life as a release hormone
B) two anterior pituitary hormones which are synergistic
C) glucagon opposing the action of insulin
D) an anterior pituitary hormone that supresses hypothalamus secretion

Answer 1

An example of negative feedback in the endocrine system is the release of glucagon opposing the action of insulin.

Step-by-step explanation:

Negative feedback is a common method of hormone regulation. It is characterized by the inhibition of further secretion of a hormone in response to adequate levels of that hormone. An example of negative feedback in the endocrine system is the release of glucagon opposing the action of insulin. When blood glucose levels are too low, the pancreas secretes glucagon, which causes the liver to convert stored glycogen into glucose, thus increasing blood glucose levels. This acts as a negative feedback mechanism to maintain blood glucose levels within a narrow range.
