Question

Why respiration considered as exothermic reaction

Answer 1

Answer:respiration is an exothermic process because energy is produced during this process.

Explanation:the food like chapati,rice and potatoes contains mainly starch carbohydrates.During digestion,starch is broken down into simpler sugar called glucose.This glucose then undergoes slow combustion by combining with oxygen in the cells of our body to produce energy in a process called respiration.
