Question

Why respiration is termed as exothermic reaction

Answer 1

Respiration is considered as exothermic reaction because energy is released in this process. Glucose combines with oxygen present in our cells to form carbon dioxide and water along with energy. Respiration is considered as exothermic reaction because energy is produced during this process.

Answer 2

Respiration is an exothermic process because in respiration Carbon dioxide present in food breaks down to form glucose. This glucose combines with Oxygen in the cells of our body and releases high amount of energy.
The reaction involves :

C6H12O6 + 6O2 →6CO2 + 6H2O + Energy

Here, C6H12O6 = Glucose, O2 = Oxygen gas, CO2=Carbon dioxide and H2O = Water.
