Question

Why is respiration considered an exothermic process?

Answer 1

In respiration, glucose undergoes slow combustion by combining with oxygen to form carbon dioxide, water and energy. Apart from other functions, this energy maintains our body heat.

C₆H₁₂O₆ (aq) + 6O₂ (g) $\to$ 6CO₂ (g) + 6H₂O (l) + Energy

Due to this production of energy, respiration is considered an exothermic process.
