Facts About Insulin

Glucose is a very large molecule. As such, it requires a special transport vehicle to move into the cells of your body for conversion to energy. Insulin is this transport vehicle. When insulin comes in contact with a cell membrane glucose is carried inside the cell. So actually, insulin is a messenger and its message is “let us in.”
In this way insulin acts to lower blood glucose levels by storing glucose.

A small amount of glucose can be stored in skeletal muscles or in the liver as glycogen. Glycogen is stored for use as an extra reserve. You might tap into your glycogen reserves during some physical activity that uses up all available glucose in your blood. Perhaps you went out for a walk or a run and had to take a detour which added unanticipated length to the route or you had an office meeting scheduled for an hour that lasted two hours. Because of these handy glycogen reserves, you had the energy to make it home in good shape or you sailed through the office meeting without losing your mental edge.
