What are the summary equations for cellular respiration?

The summary equation for aerobic respiration is C₆H₁₂O₆ + 6O₂ to 6CO₂ + 6 H₂O + 36 or 38 ATP while the summary equation for anaerobic respiration is C₆H₁₂O₆ to 2CO₂ + 2C₂H₅OH + 2 ATP. In the equations, C₆H₁₂O₆ is a type of glucose, O₂ is oxygen, CO₂ is carbon dioxide and 2C₂H₅OH is lactic acid.

Both reactions occur in cells in order to synthesize ATP, a type of energy used in cells. Aerobic respiration consumes oxygen to break down glucose through glycolysis, whereas anaerobic respiration occurs when there is no access to oxygen due to an oxygen debt after a muscle cell has used up its oxygen supply.
