Answer:
Glucose and Oxygen
Explanation:
Cellular respiration is the process whereby cells derives energy by the use of glucose and oxygen.
Organisms that use cellular respiration to produce their energy are known as heterotophs. They derive the glucose from food materials obtained from plant sources. They use the oxygen from the environment to liberate energy from the glucose obtained from feeding on plant materials.
Cellular respiration can be simply expressed as shown below:
GLUCOSE + OXYGEN → CO₂ + H₂O + ATP
The reactants are glucose and oxygen.
The products are CO₂, water and ATP
