Respiration is a process in which we inhale oxygen from the atmosphere which oxidises glucose in our body to produce carbon dioxide, water and heat is evolved.
C6H12O6(aq) + 6O2(g) ———-> 6CO2 + 6H 2O(l) + Heat
Hence, heat is evolved during respiration it is considered as an exothermic reaction.
In the course of respiration glucose is broken into carbon dioxide and energy is released. That’s why it is considered as an exothermic reaction.
C6H12O6(aq)+6O2→6CO2(aq)+6H2O(I)+Energy
