You could change the direction of the arrow, so it is pointing left (towards the reactants) instead of right (towards the products).
Work Step by Step
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. In this reaction, the reactants are glucose and oxygen, while the products are carbon dioxide, water, and ATP.
