* ATP (Adenosine triphosphate): Il s'agit de la principale monnaie énergétique des cellules. It's produced through the breakdown of glucose and other fuels.

* eau (H2O): Water is produced as a byproduct of the electron transport chain, the final stage of cellular respiration.

* Dioxyde de carbone (CO2): Carbon dioxide is produced during the Krebs cycle, another stage of cellular respiration.

While not a direct product, cellular respiration also regenerates NAD+ and FAD , which are electron carriers essential for the process to continue.
