摘要
Plants photosynthesize in order to make carbohydrates for themselves. In the process, they generate the molecular oxygen that fuels the animal world. Only now is it becoming clear how photosynthesis makes oxygen. Tucked deep in the photosynthetic center is a ratchetlike water-oxidizing clock whose every four ticks generate an O2 molecule.
