- Reactants: Carbon dioxide and water
- Products: Glucose and oxygen
- Step One: Light energy is absorbed by chlorophyll in the thylakoid membranes of the chloroplasts.
- Step Two: Water molecules are split into hydrogen ions, electrons, and oxygen gas (released as a byproduct).
- Step Three: Hydrogen ions and electrons are used to produce ATP and NADPH in the light-dependent reactions.
- Step Four: In the Calvin cycle (light-independent reactions), ATP and NADPH are used to convert carbon dioxide into glucose.
