Brainliesttt use complete sentences to explain how the mass of hydrogen is conserved during cellular respiration.

The mass of hydrogen is conserved during cellular respiration as it follows the Law of Conservation of Matter. 

The Law of Conservation of Matter states that the reactants must equal the products, which is demonstrated through the equation that demonstrates cellular respiration.

C6H12O6 + 6O2 -> 6CO2 + 6H20

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.

Hope this helps!
