What are water and carbon dioxide in the cellular respiration reaction?
They are reactants because they are present before the reaction.
They are reactants because they are present after the reaction.
They are products because they are present before the reaction.
They are products because they are present after the reaction.

The answer is A

Explanation:

water and carbon dioxide are the reactants in the cellular respiration formula because they are what the plant needs to carry out cellular respiration. Plants need water and carbon to produce sugars and oxygen which would be the products since they come after cellular respiration has been carried out.

the answer is a i just did the test
