Abstract: | Photosynthetic organisms harvest solar energy by absorbing light and ultimately transferring energy through a cascade of chemical reactions to power all cellular processes. Core components initiating this reaction cascade are the photosynthetic reaction centres Photosystem I and Photosystem II. Two recent publications on the structure of the reaction centres by Adam Ben-Shem et al. and Kristina Ferreira et al. represent a big step towards understanding the evolutionary development of the core energy conversion process and identifying the site of the water oxidation process, the source of atmospheric oxygen. |
