Question

Quizplus · Accepted Answer

Cellular respiration refers to the process by which cells break down glucose and other molecules to produce energy in the form of ATP. This process requires the use of oxygen, and is therefore directly related to the use of oxygen for cell metabolism. External respiration refers to the exchange of gases between the lungs and the external environment, while internal respiration refers to the exchange of gases between the bloodstream and the tissues. Pulmonary ventilation refers specifically to the process of breathing, or the movement of air into and out of the lungs.
