why is respiration considered an exothermic reaction ? explain .
- 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.
We take items of wheat , rice , potatoes etc. in form of food. They contain carbohydrates. During the process of digestion, carbohydrates are broken down into simpler substances such as glucose . During the process of respiration glucose molecules combine with oxygen in cells and produce energy large amount of energy. Thats why respiration is considered as exothermic reaction . THE RCTN INVLD IS -
C6H12O6 + 6 O2 --> 6CO2 + 6H2O +ENERGY
and the reaction in which heat is released along with the formation of the product is called exothermic reaction
hence respiration is called exothermic reaction
Respiration is considered as exothermic reaction because energy is released in this process.
Glucose combines with oxygen present in our cells to form carbon dioxide and water along with energy.
C₆H₁₂O₆ + 6O₂ ----> 6CO₂ + 6H₂O + energy
