The role of oxygen in cellular respiration is to make water molecules. hence, option (D) is correct.
<h3>What is Cellular respiration ?</h3>
Cellular respiration is the process in which cells break down molecules for energy.
The cells use oxygen to break down food in the form of glucose to produce water and release carbon dioxide.
During aerobic cellular respiration, glucose reacts with oxygen, forming ATP that can be used by the cell. Carbon dioxide and water are created as byproducts.
In this reaction, energy is produced in the form of ATP that is used by the cell for its various activities.
Thus the correct answer is option D.
