Answer:

c.Your cells use the oxygen to break down sugar and produce energy.

Explanation:

Oxygen is a key reactive involved in breaking down glucose molecules during the process of aerobic cellular respiration. As a product of this process, the cells produce Adenosine triphosphate (ATP) molecules, the energy coins of the cell which are used to carry out cellular activities. By breathing the oxygen molecules enter into the lungs (air sacs) and then they are carried out by the blood vessels around the body in the bloodstream, reaching each cell to be used during aerobic cellular respiration.
