Spatial variation in phosphagens concentration in cross section 1.

(A): Phosphagen concentrations were calculated at all the myofibril points in the mesh and subtracted from the spatially averaged concentration of each phosphagen (Phosgave). Box plots represent the statistical distribution of the difference between phosphagen concentration at each point and Phosgave value of each phosphagen. The zero value corresponds to the Phosgave. (B): Normalized concentration of PCr and Cr displayed as a function of local mitochondrial density at various points in the cell. PCr and Cr concentrations were normalized by a factor equivalent to the difference of PCr and Cr maximum and minimum concentrations in cross section 1.
