in terms of its role in our metabolism, glucose is
the only source of fuel our cells can use
not able to be digested, and is excreted as waste
the only nutrient that we absorb from our digested food
a small sugar commonly used as cellular fuel
a huge molecule that is used for energy storage in the body

Explanation:

Glucose is a monosaccharide (small sugar) and a major source of energy for cells through cellular respiration. Cells can use other fuels like fatty - acids and amino - acids too. Glucose is digested and absorbed, and we absorb other nutrients like amino - acids, fatty - acids etc. It is not a huge molecule for energy storage (glycogen and fat are for energy storage).

Answer:

D. a small sugar commonly used as cellular fuel
