Photosynthesis is the synthesis of organic molecules using the energy of light. For the sugar glucose (one of the most abundant products of photosynthesis) the equation is:
6CO2 + 12H2O -> C6H12O6 + 6H2O + 6O2Light provides the energy to:
The details of these processes are described in Photosynthesis: The Role of Light.
ATP and NADPH provide the energy and electrons to reduce carbon dioxide (CO2) to organic molecules.
The graphic shows the steps in the fixation of carbon dioxide during photosynthesis. These steps were worked out by Melvin Calvin and his colleagues at the University of California and, for this reason, are named The Calvin Cycle.

All the reactions of carbon fixation occur in the stroma of the chloroplast.
