steps of 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 come back to the same molecule after c..

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 osmotic hypothesis (Mitchell 1961) the ATP is synthesized on ATPase complexes..

The electrons lost by P 6 8 0 (PS-II) are taken up by P 7 0 0 (PS-I) and do not get back to P 6 8 0 i.e., unidirectional and hence it is called non- cyclic phosphorylation. The electrons pass through the primary acceptor, plastoquinone (PQ), cytochrome complex, plastocyanin (PC) and final..

Based on Hess's law Born and Haber in 1919 developed a simplified and cyclic method to correlate lattice energies of ionic crystals to other thermodynamic data. For example, the net energy changes during the formation of sodium chloride from metallic sodium and chlorine gas can be represe..

F.F. Blackman (1905) demonstrated the presence of the dark reactions for the first time. It utilises the chemical energy temporarily stored in the products of light reaction. It is also called the Calvin cycle. It is a series of reactions taking place in a cyclic manner. It can be repres..

Nomenclature of Aldehydes and Ketones - The IUPAC names of open chain aliphatic aldehydes and ketones are derived from the names of the corresponding alkanes by replacing the ending -e with -al and -one respectively. The following steps are followed: a) The longest carbon chain containing..
