WebThe Photosystem II reaction center is composed of many different proteins and pigment molecules. MORE DETAIL 2.) P680 At the heart of the reaction center is a special pair of chlorophyll molecules known as P680, that donate electrons to the photosynthetic electron transport system. WebThe reaction center of Photosystem II consists of multiple proteins and pigment molecules. At the heart of the reaction center is a special pair of chlorophyll molecules, p680 , which donate an electron to the electron transport system. In Photosystem II, the electron is then passed to a pheophytin molecule.
