The compound that is a reactant in cellular respiration is oxygen. Cellular respiration is a process that occurs in cells to produce energy in the form of ATP (adenosine triphosphate). Oxygen is one of the reactants required for cellular respiration to take place. It is consumed by cells during the process and is essential for the final step of cellular respiration, called the electron transport chain.
