The Overall Equation of Photosynthesis
Captions available
The idea
Photosynthesis converts carbon dioxide and water into a carbohydrate and oxygen, using light energy to drive the reaction forward.
In practice
Six carbon dioxide molecules and six water molecules combine, with light energy, to form one glucose molecule and six oxygen molecules.
Where people slip
This single equation summarizes dozens of actual steps — the reaction does not occur in one leap.
