Cyclic Photophosphorylation
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 h..
Photophosphorylation (Cyclic and Non-cyclic)
process of photophosphorylation 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..

Cyclic Electron Transport System
diagram of cyclic electron transport system 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..
Non-cyclic Electron Transport System
non cyclic electron transport system 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 ..

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 ex..
Excitation and Ionisation Potential
excitation potential Excitation and Ionisation Potential - An electron revolving in a stationary orbit of an atom absorbs some energy the electron may jump over to an orbit of higher energy. This process is called excitation and the atom is said to be in the excited sta..
Scope and excitement of physics
rutherfords scattering The scope of physics is very large. Physics deals with a wide variety of disciplines such as mechanics, heat and light. Study of mechanics helps us to know the forces involved in the flight of a bird, walk of a man and so on. The study of heat helps us to know the rise and fall of temperatures, wo..
Hydrogen Molecule
It is formed by the combination of two hydrogen atoms. Each hydrogen atom has one electron in 1s-orbital and, therefore, there are two electrons in hydrogen molecule. Both these electrons are to be accommodated in the lowest energy molecular orbital. Ac..

Better than great. That was the best 45 minutes i have spent on here. We got a lot done and i have a better understanding of the material. Thanks
Tutor is an excellent. I would say this tutor is an asset of Tutor Vista.. Excellent Job!!!!!!!
The tutor really touched the right methods and formulas that would help me the most as well as a helpful practice sheet to test my knowledge of the subject. Great work!
