How insulin works

How insulin works image

Insulin acts like a key, opening body cells so that glucose can enter the cell to provide a source of energy.

Insulin is like the key to a car.

  • A car needs fuel to run, but the key provides the spark that releases the fuel.
  • In your body, insulin is used to "spark" the use of glucose as fuel in your cells.
