Pheophytin is the first electron carrier intermediate in the photoreaction center (RC P870) of purple bacteria. Its involvement in this system can be broken down into 5 basic steps. The first step is excitation of the bacteriochlorophylls (Chl)2 or the special pair of chlorophylls. This can be seen in the following … Zobraziť viac Pheophytin or phaeophytin is a chemical compound that serves as the first electron carrier intermediate in the electron transfer pathway of Photosystem II (PS II) in plants, and the type II photosynthetic reaction center (RC … Zobraziť viac In biochemical terms, pheophytin is a chlorophyll molecule lacking a central Mg ion. It can be produced from chlorophyll by treatment with a weak acid, producing a dark bluish waxy pigment. The probable etymology comes from this description, with pheo … Zobraziť viac In photosystem II, pheophytin plays a very similar role. It again acts as the first electron carrier intermediate in the photosystem. After P680 becomes excited to P680 , it … Zobraziť viac In 1977, scientists Klevanik, Klimov, Shuvalov performed a series of experiments to demonstrate that it is pheophytin and not plastoquinone that serves as the primary electron acceptor in photosystem II. Using several experiments, … Zobraziť viac • Photosynthesis • Photosystem • Chlorophyll • Reaction center • P680 • Biosynthesis of chlorophyllide a (precursor to pheophytin) Zobraziť viac Web10. jún 2014 · Pheophytin and Chlorophyll are similar in there makeup.
