Many reactions are reversible, meaning that not only can reactants react to form products, but products can react to form the original reactants. This may also be referred to as a reaction going forwards or backwards. When a reaction is in chemical equilibrium, reactants are forming products at the same rate as products are forming reactants.
In this reaction, the reactants are glucose and oxygen, while the products are carbon dioxide, water, and ATP.
