Answer:
The correct answer is option C) "carbon dioxide and water".
Explanation:
A by-product is defined as a chemical synthesized in a reaction or pathway that was not desired, or was not the objective of the reaction itself. In cellular respiration, glucose is broken down to produce energy in the form of adenosine triphosphate (ATP). Through the reactions of cellular respiration, oxygen is used to break down glucose, generating the by-products of carbon dioxide and water.
