* Glucose (C6H12O6): This is the primary fuel source for cellular respiration.

* Oxygen (O2): This is the electron acceptor in the process, allowing for the breakdown of glucose and the release of energy.

In summary, the overall chemical equation for cellular respiration is:

C6H12O6 + 6O2 → 6CO2 + 6H2O + Energy (ATP)

This equation shows that glucose and oxygen are consumed during cellular respiration, while carbon dioxide, water, and energy (in the form of ATP) are produced.
