Answer:
The majority of the carbon dioxide we exhale is produced in the cell during the process of respiration.
Explanation: Carbondioxide is a waste material which is produced in the process of respiration. In respiration, glucose molecules is broken down for releasing energy with the help of oxygen molecule which produces carbondioxide, water and energy in the form of ATP. Carbondioxide is removed through lungs and energy is used by the cell.
They were named after Dogs!
They are also similar in that during both processes, ATP is produced for the cell to use. ~ Fermentation and cellular respiration differ in that fermentation does not require oxygen<span> while cellular respiration does.</span>
