Why is respiration considered an exothermic reaction ? Explain.
Energy is required to support life. Energy in our body is obtained from the food we eat. During digestion, large molecules of food are broken down the cells and provides energy. The special name of this combustion reaction is respiration. Since energy is released in the whole process, it is an exothermic process.
