The by-products of cellular respiration are water and carbon  dioxide. The water is produced at the end of the electron transport  chain by the union of oxygen with electronâ¦s and protons (hydrogen  ions) while the carbon dioxide is a by-product of the Kreb's cycle  and pyruvate decarboxylation.
In aerobic respiration in mitochondria, the passage of electrons from one molecule of NADH generates enough proton motive force to make three ATP molecules by oxidative phosphorylation, whereas the passage of electrons from one molecule of FADH2 generates enough proton motive force to make only two ATP molecules.
