Food that we eat includes carbohydrates, proteins, vitamins etc.

During digestion, carbohydrates are broken down into simpler substances called glucose.

Glucose combines with oxygen in the cells of our body to form carbon dioxide and water along with energy.

This reaction is called respiration.

Since energy is released during this process, respiration is an exothermic reaction.
