to enter the cells.It acts as the key, unlocking the receptors for glucose to enter the cells. The cells
then metabolise the glucose to give energy to the body.

Insulin Resistance

The pancreas makes enough insulin, butdue to certain factors, the insulin is not effective in transferring glucose from the blood into the cells of the body.Such a disorder is reffed to as insulin
resistance.

Factors involved can be;
* The number of receptors on each cell becomes lower than normal.
* Insulin is not able to attach itself to the receptor.
* Insulin produced may be defective.
* With the passage of time, the capacity of the pancreas to produce insulin declines.
