Answer:
Cellular respiration refers to the set of biochemical reactions take place in the cell in order to convert the energy obtained from the nutrients into ATP (adenosine triphosphate), the energy currency of a cell.
Usually, glucose and oxygen are used as the reactants which are converted in products like ATP, water, and carbon dioxide (CO₂).
CO₂ is the waste product of this process and is removed out of the body with the help of respiratory and circulatory system of the body.
Circulatory system helps in transporting CO₂ from cells to the alveolar site of respiratory system.
At alveolar site, it is exchanged with oxygen and is excreted out of the body as part of exhaled air.
So, the correct answer would be "carbon dioxide produced by cellular respiration is excreted out of the body".
