Tell us about the biological role of glucose.

Glucose is such a small and simple molecule, but it plays an important role in our lives. Glucose is important not only for humans, but also for animals, plants and microbes.

Energy molecule. The most important role of glucose is to act as an energy molecule. Several actions take place in the body that require the input of energy. For example, any physical activity involves using muscles. Muscles work through contraction, and this is associated with the expenditure of energy. The energy released from energy molecules during oxidation is stored in the form of molecules. These molecules are called high energy compounds.
