Question

why is respiration a exothermic reaction

Answer 1

Respiration is an exothermic process because it releases large amounts of energy to the surroundings. During respiration, glucose molecules are converted to other molecules in a series of steps. They finally end up as carbon dioxide and water. The overall reaction is------------> C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + 2805 kJ

Answer 2

"Respiration is considered as an exothermic reaction because energy is released in this process.

Foods containing carbohydrates, proteins, lipids, fatty acids, etc. During the digestion process, it breaks down into small glucose units and these further reacts with oxygen and releases energy. This energy is used for the metabolic activity of the body.

Exothermic reactions are those reactions in which energy is released, so, respiration reaction is considered as an exothermic reaction."
