The correct statement that describes the reaction for cellular respiration is:

The total mass of sugar and oxygen gas equals the total mass of carbon dioxide and water.

This statement reflects the law of conservation of mass, which states that mass is neither created nor destroyed in a chemical reaction. Therefore, the total mass of the reactants (sugar and oxygen) must equal the total mass of the products (carbon dioxide and water).
