Simulations for energy transfer efficiencies between donors and acceptors in lipid bilayers using the model from Fernandes et al. (2004) (Eqs. 3–6). Donors and acceptors are assumed to be located in different planes in the bilayers and energy transfer to the two lipid bilayer leaflets at the same distance (l = 18.9 Å) is considered. A value of 16 Å was used for R _e and the distance from the donor in the protein to acceptors in the annular lipid shell was assumed to be 9.5 Å. Dark and light curves correspond to results obtained with Förster radii of 20 and 40 Å, respectively. Full lines correspond to results from simulations assuming no preferential interaction with the acceptor (K _S = 1) and dashed lines correspond to K _S = 2
