​

Answer 1

Answer:

Here's Your Answer

Explanation:

Respiration is considered as exothermic reaction because energy is released in this process. Glucose combines with oxygen present in our cells to form carbon dioxide and water along with energy. Respiration is considered as exothermic reaction because energy is produced during this process.

When a chemical reaction happens, energy is transferred to or from the surroundings. When energy is transferred to the surroundings, this is called an exothermic reaction, and the temperature of the surroundings increases. Examples of exothermic reactions include: combustion reactions.
