The machinery responsible for photosynthesis -- while commonplace and essential to life on Earth -- is still not fully understood. One of its molecular mysteries involves how a protein complex, photosystem II, harvests energy from light and uses it to split water into hydrogen and oxygen. The process generates the oxygen in the air that we breathe.
