Detailed explanation-1: -The energy released is used in the synthesis of ATP. There is a slight increase in temperature during the respiration. Every living cell breaks down its food to release energy. Reactions that involve liberation of energy and increase in temperature are called exothermic reactions.

Detailed explanation-2: -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-3: -Answer: Because energy is released during the process of respiration, it is an exothermic process. The carbon dioxide in the meal is broken down into glucose during this process. This glucose reacts with oxygen in our cells, releasing a large amount of energy.

Detailed explanation-4: -The energy that is used during cellular respiration is known as ATP. ATP, or adenosine triphosphate, is a chemical compound that is essential for all living organism. Without ATP, organisms would not be able to move or live because no energy would be available for use.

Detailed explanation-5: -In this whole cycle, a total of 4 ATP molecules are generated, out of which 2 ATP molecules are utilized in the process itself this process is called endothermic reaction while the remaining 2 ATP molecules will be the net gain of the glycolysis cycle thus it is called an exothermic reaction.
