Glucose - 1.0 Hrs
Glucose is a sugar that acts as the body's main source of energy. Most of the body's cells require glucose for energy production. The brain and nervous system cells can only function when glucose levels in the blood remain within a certain range.
The hormone insulin controls the transport of glucose into the body's cells to be used as energy. We cannot live without glucose or insulin and they must be in balance. It is important that blood glucose levels remains fairly stable as severe high or low levels can be life threatening.
