The primary products of respiration are carbon dioxide (CO2) and water (H2O). However, another important product is energy in the form of ATP (adenosine triphosphate).

While CO2 is released as a waste product, ATP is essential for cellular processes, providing the energy needed for:

* Muscle contraction

* Active transport

* Protein synthesis

* Cell division

Therefore, while not as obvious as CO2, ATP is a crucial product of respiration.
