Is your breathing related to cellular respiration?

Cellular respiration and breathing are not equivalent. Cellular respiration carries out the processes of glycolysis, pyruvate oxidation and the Krebs cycle to derive energy from glucose (this can most efficiently be done in the presence of oxygen). Breathing is simply the mechanical action of the lungs, inhalation and exhalalation, with the former being the source of the oxygen required for cellular respiration.
