Explanation:
When blood glucose levels increase above set point, the hormone insulin, which is produced in the beta cells of the Islets of Langerhans in the pancreas, is secreted into the bloodstream. The insulin binds to insulin receptors on cell membranes of liver cells, which results in accelerated conversion of glucose to glycogen, and a slower conversion of glycogen to glucose. This caused blood glucose levels to fall back to normal range again.
