The chemical equation of cellular respiration primarily contains information about the relative amounts of products and reactants. The general equation for cellular respiration is:
\[ \text{C}6\text{H}{12}\text{O}_6 + 6 \text{O}_2 \rightarrow 6 \text{CO}_2 + 6 \text{H}_2\text{O} + \text{energy (ATP)} \]
This equation indicates that one molecule of glucose reacts with six molecules of oxygen to produce six molecules of carbon dioxide, six molecules of water, and energy. The equation does not provide detailed information about intermediate reactions, the formation of glucose, or specific environmental conditions.
