Respiration is an exothermic reaction (process). Why ?

Explanation

We need energy for staying alive. We get this energy from the diet (food), we eat. Food is broken down into simple substances during digestion.
For example, Rice, potatoes and bread consists of carbohydrates. These carbohydrates are broken down to form glucose. This glucose combines with oxygen in the cells of our body and provides energy. This reaction (process) is called respiration. Thus, energy is released during respiration process, it is called an exothermic reaction.
