The concentration of ATP, ADP, and Pi differ with cell type. Consequently, the release of free energy with the hydrolysis of ATP will vary with cell type. Use the following table to calculate the AG for the hydrolysis of ATP in liver, muscle, and brain cells. In which cell type is the free energy of ATP hydrolysis most negative? AG" for the hydrolysis of ATP is -30.5 kJ/mol. Assume a temperature of 37°C. Liver Muscle Brain ATP (mM) 3.5 8.0 2.6 ADP (mM) 1.8 0.9 0.7 P, (mM) 5.0 8.0 2.7
