From the blood, an insulin molecule crosses the blood vessel wall and attaches to an insulin receptor on the outer wall of a muscle, liver or fat cell. This attachment triggers the movement of glucose into the interior of the cell, where it can be converted into energy for metabolism, repair and defense.
