Why respiration is exothermic reaction in nature

Answer» Because during respiration glucose is oxidise and release energy .
In the process of respiration, the complex substances (food) are broken down into simpler substances and then converted into glucose. In this whole process, energy (or heat) is released.we know that a reaction in which heat is released along with the formation of products is known as an exothermic reaction.thus, from the above two points, respiration is an exothermic process.njoY ;)
Because food break down by respiration and releses energy
Because food is broken down to release energy.
