Answer 2

Answer: oxygen and sugar molecules

Explanation: During cellular respiration, cells produce energy through the breakdown of sugar molecules in the presence of oxygen. Cellular respiration is a process by which glucose is broken down in the presence of oxygen to produce energy, carbon dioxide and water. The energy produced in cellular respiration is used to drive other cellular processes.

The equation for cellular respiration is C6H12O6 + 6O2 --> 6CO2 + 6H2O + Energy.
