During cellular respiration, when glucose is broken down into pyruvic acid through glycolysis, the process produces not only ATP but also NADH (not listed in your options but worth noting). However, among the options you provided, none directly respond to what is produced as a result of this reaction.
If you're looking at the complete process of cellular respiration, water is produced during the electron transport chain stage as a byproduct. If we narrow it down to glycolysis specifically, then the answer is none of the given options are correct.
Please double-check your question context or provide more details to guide a more accurate response!
