Transient changes of myoglobin saturation, phosphate levels, cytoplasmic ATP hydrolysis potential, mitochondrial inner membrane potential, and mitochondrial ATP production rate in the control system. (A.) Myoglobin saturation (S_Mb). (B.) Cytoplasmic ATP concentration ([ATP]_c). (C.) Cytoplasmic creatine phosphate concentration ([CrP]_c). (D.) Cytoplasmic inorganic phosphate concentration ([Pi]_c). (E.) Cytoplasmic ADP concentration ([ADP]_c). (F.) Cytoplasmic ATP hydrolysis potential (-ΔG_ATPase). (G.) Mitochondrial inner membrane potential (ΔΨ). (H.) Mitochondrial ATP production rate, equal to mitochondrial adenosine nucleotide translocator flux (J_ANT). All variables are simulated for the time courses of the flow and ATP consumption rate in Figure 3.
