In your own words, explain what the summary equation tells you about cellular respiration.

Cellular respiration according to equation

C₂H₂O₂ + 6O₂ ⇒ 6CO₂ + 6H₂O + ATP

This equation tells that glucose molecule is broken down in the presence of oxygen into carbon dioxide, water and energy. However, its mechanism is not so simple, it complete in three steps. In first step also known as glycolysis, glucose molecule is broken down into two pyruvates with expenditure of energy. In second step and third step (Kreb cycle and ETC) most of the energy is released in the form of ATP
