Photosynthesis: Light Reactions
O2 + 4e- + 4H+. Photosystem II contains chlorophyll a, as well as up to 50% chlorophyll b. It probably evolved later as a supplement to Photo I. It is needed to capture enough energy to do the biosynthetic reactions of the dark reaction. Its reaction center is a molecule called P680 which absorbs light maximally at 680 nm. Noncyclic Photophosphorylation: Photosystem II works with Photosystem I and two series of enzymes imbedded in the thylakoid membrane to transfer energy from the form of light to that stored in chemical bands and gradients which the plant can use in a process called noncyclic photophosphorylation. It not only transfers the electrons for PS I but also is responsible for ATP production. Read more: http://www2.mcdaniel.edu/Biology/botf99/photo/l4ightrx.html">Light Reactions of Photosynthesis. ...
