The process of cellular respiration's chemical equation can be represented as follows: **C6H12O6 + 6O2 → 6CO2 + 6H2O + energy (ATP)**. This equation summarizes how glucose (a sugar) reacts with oxygen to produce carbon dioxide, water, and energy in the form of ATP (adenosine triphosphate). Cellular respiration is crucial for living organisms as it provides the necessary energy for cellular functions and metabolic processes. Understanding this process is vital for studies in biology and biochemistry.
