Figure 7
Steady-state myoglobin saturation, phosphate levels, cytoplasmic ATP hydrolysis potential, mitochondrial inner membrane potential, and mitochondrial ATP production rate in the control and no-CK systems. Simulated ranges of variables are shown as shaded regions, black for the control and grey for the no-CK system. The upper bounds of the regions represent the maximum values during a heart cycle at steady state, and the low bounds represent the predicted minimum values.
