The correct equation for cellular respiration is:
\[ \text{glucose} + \text{oxygen} \rightarrow \text{carbon dioxide} + \text{water} + \text{energy} \]
In chemical form, this is often represented as:
\[ C_6H_{12}O_6 + 6O_2 \rightarrow 6CO_2 + 6H_2O + \text{energy} \]
So the answer is: Glucose + Oxygen → Carbon Dioxide + Water + Energy.
