Describe how insulin returns the blood glucose concentration to normal.

Insulin acts a key to open the way for glucose to enter cells (hepatocytes, muscles and brain cells)Hepatocytes absorbs more glucose from blood. Glucose converted to glycogen- for storageLiver cells respire more glucose/faster rate of respirationMore is required to explain how insulin return blood glucose to normal upon a shift from equilibrium and a change from baseline function.This falls within Homeostasis and responseOther examples include:Thermoregulation, Osmoregulation and Urea cycle
