Crystal Structure Of Photosystem I: A Photosynthetic Reaction Center and Core Antenna System From Cyanobacteria: Reenergizing Those Electrons!
Cartoon with hydrogen bonds
Photosystem I utilizes sulfur clusters as electrons are literally passed through Photosystem I in bioenergetic chemical reactions. As can be seen, several sulfur clusters are present throughout Photosystem I.
