Diffusion coefficients (μm2s–1) for important molecules used in previous(Tombes et al., 1987) and the present simulations. As previously calculated, diffusion coefficients of ADP and AMP were regarded as identical to that of ATP, since their relative molecular masses (Mr) are close to each other. Also, the diffusion coefficient of phosphocreatine (PCr) was regarded as identical to that of creatine (Cr). As the diffusion coefficient for ATP was set to 60μm2s–1 (40% of that in the previous calculation), the diffusion coefficients for Cr and PCr were similarly set to 40% of the values used previously
