Oxidation Reduction Reaction in Photosynthesis Light reaction,Where redox Gibb's Free Energy is Stored in the form of Adenosine Triphosphate in the Photophosporylation reaction.


Camera & Photo

Today i will continue from Redox reaction in Bio chemistry.
We will see that the Spontaneous Redox Reaction whose Gibb's Free Energy is negative or equal to zero.

\Delta H - T \Delta S_{int} \le 0 \,
 Let the change ΔG in Gibbs free energy be defined as
\Delta G = \Delta H - T \Delta S_{int} \,  then
\Delta G < 0 \, favoured reaction (Spontaneous) reaction
Which is defined in terms of redox reduction potential as
                                \Delta G^\circ = -nFE^\circ \,

Useful identities


\Delta G = \Delta H - T \Delta S \, <0, for Spontaneous Reaction

\Delta_r G^\circ = -R T \ln K \, ,Where K=Equilibrium constant

\Delta_r G = \Delta_r G^\circ + R T \ln Q_r \, Qr=Reaction Quotient in Chemical reaction
Qr=K ,when Change in Gibb;s free energy is equal to zero





\Delta G = -nFE \,
\Delta G^\circ = -nFE^\circ \,<0, For Spontaneous Redox Reaction
          and rearranging gives
nFE^\circ = RT \ln K \,
nFE = nFE^\circ - R T \ln Q_r \, \,
 E = E^\circ - \frac{R T}{n F} \ln Q_r \, \,                                                                                                              

These are some Equations helpful to understand the relation among Gibb's free Energy change,Equilibrium constant and Spontaneity of Redox reaction in Photosynthesis light reaction.
This Gibb's Energy change ie \Delta G^\circ = -nFE^\circ \,<0 , during redox reaction which is photosynthesis light reaction gets stores in ATP Phosphodiester  bond  as dealt in my previous lecture and blog. Whose figure i can show now

  Okey come to our topic of Photosynthesis light reaction
                                                                 

                                                                                                          
                                                                                                                                                                                                                 

























Conclusion
It is the negative of Gibb's free energy change in Redox reaction which gets stored in the form of ATP during Photo-phosphorylation reaction in Photosynthesis Light Reaction.

I will deal with many correlated topics  in Engineering, Bio chemistry ,Mathematics,Physics and Chemistry in the coming Session which will have a common origin.

General theory of relativity says that the Gravitational Conservative field is the Convex downward curvature of Space time 4D Geometry and Gravitational Force is the push caused by convex downward curvature.
