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 Vgr=GMJm/REu and defines the maximal value Δ Emax 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 dEu from Jupiter is dEu= 105.3× RE to be compared with the radius RJ=10.97 RE of Jupiter. The mass of Jupiter is MJ= 317.8ME. This gives Δ Emax,Eu/Δ Emax,E=Vgr,J/Vgr,E= (MJ/ME) × (RE/dEu)≈ 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=dEu. If a proton triplet defines the metabolic energy quantum, one would have h=(1/5)REu.

Solar radiation should provide the metabolic energy. The average distance dJ of Jupiter from Sun varies between 5.0AU and 5.4AU so that the gravitational metabolic energy quantum has upper bound Δ Egr,Sun,J \leq Δ Egr,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.
