The chemical equation of cellular respiration primarily contains information about the relative amounts of products and reactants. The overall equation for cellular respiration can be summarized as:
\[ \text{C}6\text{H}{12}\text{O}_6 + 6\text{O}_2 \rightarrow 6\text{CO}_2 + 6\text{H}_2\text{O} + \text{energy (ATP)} \]
This equation indicates the reactants (glucose and oxygen) and the products (carbon dioxide, water, and energy), showing their relative amounts.
