Imagine that creatine phosphate, rather than ATP, is the universal energy carrier molecule in the human body. Assume that the cellular concentrations of creatine phosphate, creatine, and phosphate are 21.7 mM, 2.17×10-3 mM, and 6.30 mM, respectively. Calculate the weight of creatine phosphate that would need to be consumed each day by a typical adult human if creatine phosphate could not be recycled. Estimate the free energy of hyrdolysis of creatine phosphate under cellular conditions to determine how many moles are required. Use the standard…
