The reactant are oxygen and carbohydrate (glucose).
Cellular respiration is a redox reaction that extracts energy from glucose. We will have a controlled release of the free energy of organic compounds from the cells to form ATP.
Can be done in the presence (aerobic) or absence (anaerobic) of oxygen.
The aerobic reaction will produce carbon dioxide (CO2) and water (H2O).
Reactants are the molecules that begin cellular respiration, in this case that would be oxygen<span> and </span>glucose<span>. Hope this helps. </span>
