Question 4

When blood sugar rises after a meal,the pancreas releases insulin.This causes cells to take up excess glucose.When blood sugar falls,glucagon is released from the pancreas.This causes cells to break down glycogen into glucose,which is then released into the blood.Which of the following aspects of this system best explains why it is an example of homeostasis?

A)  The release of insulin causes blood sugar levels to fall. 
B)  The release of glucagon causes blood sugar levels to rise. 
C)  The pancreas and liver work together as an organ system. 
D)  The system works to keep blood sugar levels within a narrow range. 
E)  Insulin and glucagon are enzymes that only work within a narrow range of temperatures.
