Results of computer simulations run using the reduced BioModel for mitochondrial energy metabolism and 3D spatial models, as described in text. Rows correspond to spatial models with (A) lamellar, (B) tubular and (C) no cristae, respectively, shown in first box of each row. The second and third boxes in each row are slices from 3D maps of ADP concentration, [ADP], outside matrix and of ANT flux, J(ANT), on the inner membrane for each model at steady state.
