MC calculations of AV-CL relative quantum yield for the cases of the basic lipid demixing model (dash-dot-dotted line), the basic demixing model allowing for complete protein binding (Case I, dash-dotted line), cyt c location in the lipid bilayer center (Case II, dotted line), and aggregation of membrane-bound protein (Case III, dashed line). The experimental curve was obtained for PC/CL (2.5 mol % CL) liposomes at ionic strength 40 mM with donor AV-CL.
