Expert Answer
We get energy from food that we eat. This food is broken down into simple substances thro' digestion process. Carbohydrates present in food are broken down to form glucose. This glucose combines with Oxygen in the cells of our body and provides energy. This reaction is known as respiration.
C6 H12O6 + 6 02 (g) ? 6 CO2 (g) + 6H2O (l) + energy
Glucose
Hence, respiration is considered as an exothermic reaction.
