During movement, muscle cells require large amounts of ATP to fuel their contractile apparatus. These cells contain high levels of creatine phosphate (Figure Q13–11), which has a standard free-energy change (ΔG°) for hydrolysis of its phosphate bond of –43 kJ/mole. Why is this a useful compound to store energy? Justify your answer with the information shown in Figure 13–8.
