उत्तर
The process of respiration is an oxidation reaction which is exothermic.
Explanation:
An oxidation reaction, which is exothermic: Respiration is an oxidation reaction because glucose (C6H12O6) chemically reacts with oxygen to break down into carbon dioxide and water. It is highly exothermic because this metabolic breakdown releases substantial chemical energy as heat and ATP, fueling living cells.
