Describe the role of insulin in regulating blood sugar levels

Insulin helps control blood glucose levels by signaling the liver + muscle fat cells to take glucose from the blood. It then helps the cells to take the glucose to be use for energy, and if the body has sufficient energy, insulin signals the liver to take up glucose and store it as glycogen.

there are so many examples for that in different areas, like biology experiment carried out in our lab recently.
