cyclic and non cyclic photophosphorylation animation

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)..

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..

Summary - The circulatory systems circulate nutrients, wastes and metabolic intermediates and heat uniformly through out the body. Advanced animals carry blood as the circulating fluid and a circulatory system with the heart and blood vessels to conduct the blood. In invertebratessuch as ..

Electron Transport System - 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..

Equation of photosynthesis ..

In an ecosystem there are two processes proceeding simultaneously: 1 ) Energy flow and 2 ) Biogeochemical cycle The energy flow is in a single direction and is non-cyclic where as Biogeochemical flow is cyclic (Any mineral cycl..

There are millions of organic compounds and this makes it physically impossible to study each individual compound. To facilitate their study, organic compounds are classified into various groups and sub-groups. They may be broadly classified into the following classes: Open chain or acyclic compoun..

Organic materials synthesised by the producers are eaten and assimilated by the consumers. With the help of decomposers, all the organic materials in the bodies of the consumers are eventually broken down into inorganic materials. These are then rebuilt into organic compounds by the synthetic activ..
