Question

Why respiration is an exothermic reaction?

Answer 1

Respiration

1. Organic substances release energy through respiration, which is a chemical process.
2. Exergonic reactions transform the molecules into new one.

Respiration is an exothermic reaction

1. The nutritional value of a food refers to the nutritional content as well as the amount of nutrients present in that food and how that food will affect our bodies.
2. Some foods are high in protein, such as meat and fish, while others, such as eggs and oranges, are high in vitamins.
3. Carbohydrate-rich foods include rice, wheat, and other grains.
4. Carbohydrates are carbon, oxygen, and hydrogen-containing macromolecules.
5. Sugar or glucose are the two terms for the same thing.
6. Carbohydrate-rich foods are broken down into simpler glucose molecules when we eat them.
7. As we all know, when we breathe, we take in oxygen and expel carbon dioxide.
8. When glucose is combined with oxygen, it undergoes a combustion process that releases water and carbon dioxide, which is the same carbon dioxide that we exhale.
9. This entire process generates a great deal of heat, which is the energy we obtain from the food.
10. An exothermic reaction is one in which heat is produced as a byproduct of the process.
11. As a result, respiration is an exothermic reaction in which the heat created is transported throughout the body as energy, which is why we feel warm when we exhale.
12. When we breathe out, the air that leaves our bodies is heated.
13. The reaction produces heat as a by-product in an exothermic reaction..
