The correct equation for cellular respiration is:
6O₂ + C₆H₁₂O₆ --> 6CO₂ + 6H₂O + ATP Energy
This equation represents the process by which glucose (C₆H₁₂O₆) and oxygen (O₂) are converted into carbon dioxide (CO₂), water (H₂O), and ATP (adenosine triphosphate) energy, which cells use to perform various functions.
