Imagine that inside a cell the [creatine phosphate] = 3.5 mM,[creatine] = 0.6 mM, and [Pi] = 4.3 mM. Furthermore, imagine thatthe pH inside the cell is 7.4. Given that ΔG°′ for creatinephosphate hydrolysis is -10.3 kcal/mol, what is the ΔG for creatinephosphate hydrolysis inside the above-described cell, which is at37 °C? Report your answer in kcal/mol to the nearest tenths. Hint:you might wish to consult the chapter in our text that discussesthermodynamics.
