Answer:
The only molecule in the group that is not a product of cellular respiration is C₆H₁₂O₆ (option c).
Step-by-step explanation:
C₆H₁₂O₆ is the glucose molecule, which is an energetic substrate and not a product of cellular respiration.
Cellular respiration is the process by which, through the oxidation of glucose and in the presence of oxygen, energy is obtained in the form of ATP. The reaction that summarizes this process is:
C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + Energy (ATP)↑
As can be seen in the diagram, while glucose and oxygen are substrates of the reaction, the resulting products are CO₂, H₂O and energy.
