Which of the following are the final by-products of glucose oxidation during aerobic cell respiration?

Question

A. ATP only
B. heat only
C. carbon dioxide only
D. both ATP and heat only
E. ATP, heat, and carbon dioxide

I know that the following equation is true of the oxidation of a molecule glucose:

6O2 + C6H12O6 --> 6H2O + 6CO2 + 38ATP

From this, I see that carbon dioxide and ATP are products. The question asks for "final by-products," so are these two considered by-products in this reaction? If these two ARE considered by-products, then the only answer that would work is E. This would mean that heat is also a by-product. Is that true then?

Answer 1

If so, then the answer is E. ATP, heat, and carbon dioxide.
