The free energy change ([DELTA]G) of a protein folding reaction can be calculated via, [DELTA]G = [DELTA]H - T[DELTA]S (1) Where [DELTA]G is the Gibbs free energy (J/mol), [DELTA]H is enthalpy (J/mol), T is the temperature in Kelvin (K), and [DELTA]S is the entropy (J/mol K).
This leads us to the Gibbs free energy G, (not to be confused with shear modulus G) which defines the maximum work a process can perform under a constant pressure thus; G = H - TS 3 Gibbs free energy G is equal to heat content (enthalphy H) minus temperature T times entropy S.
The photons would recharge all the electric and concentration gradients, all the proteins would become regenerated and re-polarized, the Gibbs free energy would be increased to a large enough value that it may easily decrease and so all the important chemical reactions are available again for the biological coupling processes.
