14 The concentrations of ATP, ADP, and P; differ with cell type. Consequently, the release of free energy from ATP hydrolysisvaries with cell type. Use the table to calculate the free energy change, AG, of ATP hydrolysis in liver, muscle, and brain cells.Cell typelivermusclebrainATP (MM) ADP (MM)ΟΟ3.58.02.6AG of ATP hydrolysis in liver cells:Oliverbrainmuscle1.80.90.7AG of ATP hydrolysis in muscle cells:AG of ATP hydrolysis in brain cells:The expression for free energy change isAG = AG" + RT In (Q)The standard free energy, AG", of ATP hydrolysis is -30.5 kJ · mol¯¹.The product of the gas constant and temperature, RT, is 2.47 kJ - mol¯¹.P₁ (MM)5.08.02.7In which cell type does ATP hydrolysis release the most energy?kJ. mol-1kJ. mol-¹kJ. mol-1

Since conditions inside the cell are different than standard temperature and pressure, biochemists use a different set of standards called the biochemical standard state: at pH =7 and [H2O] = 55.5 M and for reactions that require Magnesium [Mg2+] = 1MStandard free energy change calculated at biochemical standards is called biochemical standard free energy change and is denoted by ΔG'° (delta G prime knot). K'eq is the equilibrium constant at biochemical standards and is related to biochemical standard free energy change:ΔG'° = -R T ln K'eqWhere R is the universal gas constant equal to 8.314 J mol-1 K-1, T is the standard temperature of 298 K and K'eq is the equilibrium constant at biochemical standards.The actual free energy change (ΔG) is related to biochemical standard free energy change by the following expression:ΔG = ΔG'° + R T ln Qwhere Q is the mass action ratio ([product]/[reactant]) of the reactant and products in the sample.As per the question, standard free energy change = 30.5 kJ/molRT = 2.47 kJ/molQ = [ADP] + [Pi] / [ATP] = 1.8+5.0 / 3.5 = 1.94ΔG = ΔG'° + R T ln QΔG = -30.5 kJ/mol + 2.47 kJ/mol * ln 1.94ΔG = -30.5 kJ/mol + 1.64 kJ/mol ΔG = -28.86 kJ/molAs per the question, standard free energy change = 30.5 kJ/molRT = 2.47 kJ/molQ = [ADP] + [Pi] / [ATP] = 0.9+8.0 / 8.0 = 1.1125ΔG = ΔG'° + R T ln QΔG = -30.5 kJ/mol + 2.47 kJ/mol * ln 1.1125ΔG = -30.5 kJ/mol + 0.26 kJ/mol ΔG = -30.24 kJ/molAs per the question, standard free energy change = 30.5 kJ/molRT = 2.47 kJ/molQ = [ADP] + [Pi] / [ATP] = 0.7+2.7 / 2.6 = 4.86ΔG = ΔG'° + R T ln QΔG = -30.5 kJ/mol + 2.47 kJ/mol * ln 4.86ΔG = -30.5 kJ/mol + 3.9 kJ/mol ΔG = -26.59 kJ/molFree energy change of ATP hydrolysis is: -28.86 kJ/mol, -30.24 kJ/mol and -26.59 kJ/mol in liver, muscle and brain cells. respectively.Since the actual free energy change for muscle cells is lowest (most negative), ATP hydrolysis releases most energy in muscle cell.
