primary acceptor of electrons in non cyclic photophosphorylation

The electrons released by P 7 0 0 of PS-I in the presence of light are taken up by the primary acceptor and are then passed on to ferredoxin (Fd), plastoquinone (PQ), cytochrome complex, plastocyanin (PC) and finally back to P 7 0 0 i.e., electrons com..

Photophosphorylation (Cyclic and Non-cyclic) - Photosynthetic phosphorylation or photophosphorylation is the process of phosphate group transfer into ADP to synthesize energy rich ATP molecule making use of light as external energy source. According to chemi ..

The light energy of specific wavelengths is absorbed by chlorophylls and accessory pigments of PS-II. These pigments transfer their absorbed energy to PS-II reaction centre - P 6 8 0 (chlo 680). This centre become photo excited and exudes an electron with a gain of energy (23 K Cal/mol..

Cylic reaction transport occurs only occasionally when synthesis of carbohydrate is curtailed due to limited supply of CO 2 and NADPH 2 starts accumulating. At this time, there would be no need for additional NADPH 2 . Moreover, the cyclic electron transport serves the purpose o..

Electron transport chain refers to the light driven reactions of photosynthesis. They were first formulated in 1939 by Robert Hill. The two photosystems are connected in series with each other by the components of electron transport system. The reaction centres become so excited..
