Question

How we can say that respiration is an exothermic chimical reaction?

Answer 1

because in respiration the heat is liberated by the oxidation of glucse

Answer 2

Hello friends!!

Here is your answer :

Exothermic reaction : These reaction proceed with the evolution of heat or energy

We require energy to stay alive, we get this energy from the food we eat. During digestion, food is broken down into simpler substances. Food generally contains carbohydrates . These carbohydrates are broken down to form glucose. This glucose combines with oxygen in the cells of our body and provides energy. The whole process is called respiration and it is evident that heat is released in the form of energy. Hence, respiration is called exothermic process.

C6H12O6 (s) + 6O2 (g) ➡️ 6CO2(g) + 6H2O (l) + Energy
