Why is Respiration Considered an Exothermic Reaction Explain

Question: Which of the following is a reason why respiration is considered an exothermic reaction?

  1. Respiration releases energy in the form of heat.
  2. Respiration requires energy from food.
  3. Both A and B
  4. None of the above

Answer: C. Both A and B


Respiration is an exothermic reaction because it releases energy in the form of heat. This energy is used to power all of the activities of our cells, from building new molecules to transporting materials across membranes.

Respiration is considered an exothermic reaction because it releases energy. When living organisms undergo the process of respiration, they break down organic molecules, such as glucose, to produce energy in the form of adenosine triphosphate (ATP). This energy is essential for various cellular activities, allowing organisms to carry out functions like growth, repair, and movement.

During respiration, the chemical bonds in glucose are broken, and the released energy is harnessed by the cells.
