The creation of ATP is the whole point of this process. But, carbon dioxide and water are also created. Carbon dioxide and water are the by-products of cellular respiration. These are substances that are created in cellular respiration but are not needed.
The only chemical by-products produced by aerobic respiration -- carbon dioxide and water -- are simple for the human body to deal with. However, anaerobic respiration that occurs in muscle cells during times of extremely intense physical activity causes glucose molecules to break down into ATP and lactic acid.
