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

Glucose and oxygen are required for cellular respiration. As the law of conversation states, in a biochemical reaction, mass is conserved. For every glucose molecule, 6 oxygen molecules are used up and the end products, other than the energy dissipated by the reaction, are 6 water molecules and 6 carbon dioxide molecules. The mass of hydrogen in the glucose is therefore conserved in the water molecules products.

The answer is observations and interpreting.
