Which one of the following choices is not a function of water?
a. carrying food through the digestive system
b. transporting nutrients to cells and tissues
c. serving as a shock absorber and cleaning agent
d. providing caloric energy in the body

D. Providing caloric energy in the body

Explanation:

Water is important in the body because the body uses water in all its organs, cells and tissue in regulating its temperature and maintaining other bodily functions. Water does not provide caloric energy in the body because it does not contain fats, carbohydrates or proteins and as a result does not contain any calories. It does not add or provide calories to the body but it is essential to the body's energy system because it helps in transporting energy from the breakdown of foods into the human cells.
