Model-predicted steady-state cation concentrations in the mitochondrial matrix and corresponding $\mathrm{\Delta }{G^{\prime }}_{\text{eq}}^{\text{o}}$ of ATP hydrolysis, AKGD, and CITS at various work rates in the heart in vivo. (A) Changes in [H⁺]_x, [Mg²⁺]_x, and [K⁺]_x, where subscript “x” denotes the mitochondrial matrix. (B) Changes in $\mathrm{\Delta }{G^{\prime }}_{\mathit{ATPase}}^0$ of ATP hydrolysis (ATPase), AKGD, and CITS.
