The food we take is broken down into simple substances, Rice, potatoes and bread contain 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 is called respiration.
`underset("Glucose")(C_6H_(12)O_6(aq))+6O_2(aq) rarr 6CO_2(aq)+ 6H_2O(l)` + energy
Since energy is released in this reaction, therefore it is considered as an exothermic reaction.
