Includes photosystem ii p680
WebAt the core of photosystem II is P680, a special chlorophyll to which incoming excitation energy from the antenna complex is funneled. One of the electrons of excited P680* will be transferred to a non- fluorescent molecule, which ionizes the chlorophyll and boosts its energy further, enough that it can split water in the oxygen evolving ... WebPhotosystem II: Redox and Protein Components J. Barber, in Encyclopedia of Biological Chemistry (Second Edition), 2013 P680 P680 is composed of chlorophyll a molecule which, after excitation by the absorption of light to form P680*, gives up an electron to an acceptor, converting it to P680 •+.
