Light reactions capture energy
Pigments absorb light and help generate chemical energy carriers.
Carbon fixation builds organic molecules
A separate set of reactions incorporates carbon dioxide into carbon compounds.
Oxygen is released
The oxygen produced by oxygenic photosynthesis comes from splitting water molecules.
Photosynthesis supports food webs
Plants, algae and some bacteria convert incoming light into chemical energy used throughout ecosystems.
