Glucose is the most important simple sugar in human metabolism because it is the primary source of energy for most cells of the body and is particularly required by the brain.
Q: Where does glucose get energy?
A: The energy in glucose originally comes from the sun. Plants capture and bind the sun’s energy by means of photosynthesis. We eat the plants directly or indirectly by eating food from animals that have eaten plants.
Energy from glucose is obtained in the body from its reaction with oxygen (oxidation) that occurs in power producing mitochondria within cells.1
Humans cannot live without an adequate supply of glucose to the body.
