Gradients of ADP concentration, [ADP], and ANT flux, J(ANT), were established inside cristae during steady state. Values are presented for [ADP] and J(ANT) at the crista openings (proximal) and at the farthest end of the cristae from the openings (distal) for spatial models with cristae of different length, LCRIS, and different values of the forward rate constant for the surrogate kinase reaction, kf. 3D TOMO refers to the three-dimensional crista model extracted from an EM tomogram of a mitochondrion (described in text). The other simulations used idealized 2D and 3D spatial models based on those in Fig. 3, Fig. 5. Numbers in parentheses in first column refer to figures in the text with typical results for that spatial model. Abbreviations: LAM, lamellar cristae; TUB, tubular cristae.
