Detailed explanation-1: -Respiration is a kind of burning fuel. During respiration, Carbohydrates present in food are broken down to form glucose. Glucose combines with oxygen in the cells of our body and provides energy. Therefore, respiration is an exothermic reaction.
Detailed explanation-2: -Respiration is a series of exothermic reactions that occur in the mitochondria of living cells in order to release energy from food molecules.
Detailed explanation-3: -During respiration, the simpler compounds obtained during digestion are burned to get energy required for various processes. So, respiration is an exothermic reaction since energy is getting released.
Detailed explanation-4: -C6H12O6+6O2→6CO2+H2O+energy (ATP)
Detailed explanation-5: -Best Answer Ans. In the process of respiration, the glucose combines with oxygen in the cells of our body to form carbon dioxide and energy is released. That’s why it is considered an exothermic reaction.
