Jupiter's Moon Europa as a candidate for a seat of life

Jupiter's moon Europa is one of the most promising candidates for a seat of life since it contains water in the form of ice. Is quantum gravitational metabolism based on the solar and Jovian gravitational fields consistent with Earth-like metabolism?

For the Jupiter's gravitational field, the gravitational potential energy at the surface of Europa is V_gr=GM_Jm/R_Eu and defines the maximal value Δ E_max of the metabolic energy quantum for a flux loop defining dark gravitational HB oriented radially outwards along A line connecting Europa and Jupiter. The mean distance d_Eu from Jupiter is d_Eu= 105.3× R_E to be compared with the radius R_J=10.97 R_E of Jupiter. The mass of Jupiter is M_J= 317.8M_E. This gives Δ E_max,Eu/Δ E_max,E=V_gr,J/V_gr,E= (M_J/M_E) × (R_E/d_Eu)≈ 3.0.

For a single gravitationally dark proton, the maximal metabolic energy gain would be .99 eV, which is twice the metabolic energy quantum. Standard metabolic energy quantum .5 eV corresponds to a radially oriented loop with height h=d_Eu. If a proton triplet defines the metabolic energy quantum, one would have h=(1/5)R_Eu.

Solar radiation should provide the metabolic energy. The average distance d_J of Jupiter from Sun varies between 5.0AU and 5.4AU so that the gravitational metabolic energy quantum has upper bound Δ E_gr,Sun,J \leq Δ E_gr,Sun,E/5≈ .5 eV, which corresponds to metabolic energy quantum. Photosphere produces IR radiation with energies in the range .4-.6 eV. Therefore Europa seems to satisfy the conditions from quantum gravitational metabolism.
