To effectively illustrate the process of cellular respiration, the correct components to include in the model are:
Inputs: glucose and oxygen Outputs: water, carbon dioxide, ATP
This reflects the overall equation for cellular respiration: \[ \text{C}6\text{H}{12}\text{O}_6 + 6 \text{O}_2 \rightarrow 6 \text{CO}_2 + 6 \text{H}_2\text{O} + \text{ATP} \]
Thus, the first option is the correct choice.
