How glucose reach the cells?
Glucose is a very important biological molecule, as it is the brain's primary source of energy and a significant source of energy for all body cells. The circulatory system helps move glucose out of the digestive tract and into the body cells.

The major function of the biomolecule glucose is to provide energy to cells. Body cells take up glucose from the blood and chemically burn it, yielding energy molecules that they can use to fulfill cellular functions. Some cells, such as those of the liver and muscles, store glucose and release it under fasting conditions.

Glucose first moves into the bloodstream upon absorption from the intestine. Specialized cellular transporters called sodium-dependent hexose transporters shuttle glucose across the cells that line the intestinal tract.
