Answer: energy)
Explanation:
Most living things produce ATP for their energy needs through cellular respiration. In this process, fatty acid or glycid molecules, especially glucose, are degraded, forming gas molecules (CO2) and water (H2O) and releasing energy, which will be used in the production of ATP molecules from ADP and Pi.
If we compare glucose respiration reagents and products with those of their combustion, we see that the processes are equivalent. In either case, one glucose molecule reacts with six oxygen gas molecules, producing six carbon dioxide molecules and six water molecules.
C6H12O6 + O2 ⇒ 6 CO2 + 6 H2O
