Use complete sentences to explain how the mass of hydrogen is conserved during cellular respiration.
erma4kov [3.2K]

Answer:

The mass of hydrogen is conserved during cellular respiration as it follows the Law of Conservation of Matter. This shows that hydrogen has been conserved throughout the entire process (H representing Hydrogen) as the product has the same amount of hydrogen as the reactants.

The AMOUNT of carbon-dioxide atoms released by respiration are EXACTLY EQUAL to the atoms of these materials contained in the oxygen and carbon converted. In this way respiration has conserved the mass or material and in this way followed the law of conservation of mass.
