Which of these best describes a negative feedback control mechanism?
A)High blood glucose causes pancreatic secretion of insulin.
B)Insulin causes the liver to store glucose as glycogen.
C)Low blood glucose inhibits pancreatic secretion of insulin.
D)When the pancreas is not secreting insulin,it is secreting glucagon.

Question

Quizplus · Accepted Answer

A negative feedback control mechanism involves the inhibition of a process in response to a certain condition. In this case, low blood glucose inhibits the secretion of insulin from the pancreas, which helps to prevent further decreases in blood glucose levels. Option A is incorrect because it describes a positive feedback mechanism, in which an increase in a certain condition leads to an increase in a process. Option B is also incorrect because it describes a process that is not directly related to the regulation of blood glucose levels. Option D is incorrect because it describes a different hormone (glucagon) and does not involve negative feedback.
