Respiration is an exothermic reaction as it involves combustion of glucose with oxygen in the cells of the body releasing heat energy that is used by cells to perform various functions such as muscle contraction, nerve impulse transmission, and protein synthesis. The equation for respiration reaction is:
C6H12O6 + 6O2 ⟶ + 6CO2 ↑ + 6H2O + Heat energy
