Photosynthesis
Photosynthesis turns sunlight into chemical energy and releases the oxygen we breathe. Light-harvesting complexes collect photons and pass the energy to reaction centers, where it drives electron transfer across a membrane. Photosystem II splits water, and the enzyme Rubisco then fixes carbon dioxide into sugar.
