Explanation:

To determine the missing reactant and product in the cellular respiration equation:

Step 1: Recall the cellular respiration equation

The general equation for aerobic cellular respiration is:
$$\ce{C6H12O6 + 6O2 -> 6CO2 + 6H2O + ATP}$$

Step 2: Identify the missing reactant

In the given equation (\(\ce{C6H12O6 + \_ -> CO2 + \_ + ATP}\)), the reactant missing is oxygen (\(\ce{O2}\)). For aerobic respiration, glucose (\(\ce{C6H12O6}\)) reacts with oxygen.

Step 3: Identify the missing product

The product missing (other than \(\ce{CO2}\) and \(\ce{ATP}\)) is water (\(\ce{H2O}\)). Aerobic respiration produces carbon dioxide, water, and ATP from glucose and oxygen.

Final Equation

Substituting the missing reactant and product, the equation becomes:
$$\ce{C6H12O6 + 6O2 -> 6CO2 + 6H2O + ATP}$$

Answer:

Missing reactant: \(\boldsymbol{\ce{O2}}\) (Oxygen)
Missing product: \(\boldsymbol{\ce{H2O}}\) (Water)
