FIGURE A7 — Rate of the mitochondrial Na⁺/Ca²⁺ antiporter and Ca²⁺ uniporter. In A the rate of the Na⁺/Ca²⁺ antiporter, V_NaCa, is analyzed for its dependence on [Ca²⁺]_m at different ΔΨ_m with the following parameter values: [Ca²⁺]_i = 0.2 μM, = 0.051 mM s⁻¹ (see Eq. 39). B shows the dependence of Ca²⁺ uniporter as a function of the [Ca²⁺]_i at various ΔΨ_m with mM s⁻¹. The remainder of the parameters involved in Eqs. 38 and 39 are described in Table 3.
