What is the Reason Respiration is Considered an Exothermic Reaction?

By Esha Dhawan|Updated : September 21st, 2022

Do you know what is an exothermic reaction? It is a chemical reaction that produces heat and energy. Then why is respiration considered an exothermic reaction explain? Well, that is because a huge amount of heat and energy are released along with the other products in the process of respiration. Therefore, the air that we release while breathing is warm because it is a by-product of the reaction.

Answer:

Respiration is considered an exothermic reaction because it releases a large amount of heat and energy.

Respiration is equivalent to the burning of fuel. How? Because it involves the burning of sugar or glucose along with oxygen within our cells to produce the energy required for all other reactions and processes.

Furthermore, the energy that we require to function comes from the food we eat. And during digestion, the food particles are broken down into simpler components and there is an evolution of heat. This is why is respiration considered an exothermic reaction explain. 

Here is the chemical equation that explains the process of respiration:

C6H12O6 + 6O2 → 6CO2 + 6H2O + energy

Summary:

Why is Respiration Considered an Exothermic Reaction Explain?

Respiration is considered an exothermic reaction because it results in the production of heat and energy. Any chemical reaction that results in an increase in temperature is considered an exothermic reaction. 

During respiration, sugars or carbohydrates we eat are broken into simpler components called glucose. After combustion with oxygen, the glucose gives CO2 gas, H2O plus heat. This is the reason why is respiration considered an exothermic reaction.
