ATP should be less than 1M because the value of Kc is very high and reactant should be almost negligible
ADP should be greater than 1 M as almost all the reactant is converted to product
Pi should be greater than 1 almost all the reactant are converted to product

The value of the standard free energy (∆G°’) for the hydrolysis of ATP (ATP + H2O -> ADP + Pi) is relatively difficult to determine because of the small concentration of ATP remaining at equilibrium. The value can be determined from the equilibrium constant of two related chemical reactions. Glucose-6-phosphate + H2O -> glucose + Pi ; k’eq = 270 ATP + glucose -> ADP + glucose-6-phosphate ; K’eq = 890 From this information, calculate the standard free energy of...
Calculate the actual free energy of synthesis of ATP in human erythrocytes. The standard free energy of hydrolysis of ATP is -30.5 kJ/mol, and the concentrations of ATP, ADP, and Pi in an erythrocyte (all in M) are as follows: [ATP] = 2.25 X 10 –3; [ADP] = 0.25 X 10-3; and [Pi] = 1.65 X 10–3. Assume that the temperature is 37 oC and the pH is 7.0.
4. Consider the following reaction: ATP + pyruvate phosphoenolpyruvate + ADP Given: Standard free energy of hydrolysis for ATP to ADP is -30.5 kJ/mol Standard free energy of hydrolysis for phosphenolpyruvate to pyruvate is -61.9 kJ/mol Calculate AGⓇ and Key for this reaction.
To answer this question, please reference the Problem Solving Video: Free Energy, ATP, and Creatine in Resting Muscles. The standard free energy, AGⓇ', value for an enzymatic reaction with several al components is the sum of the AGⓇ values for each component. Creatine kinase catalyzes the transfer of a phosphate group from creatine phosphate to ADP to form ATP. Standard Free Energy of Hydrolysis Standard E Compound kJ.mol-1 creatine phosphate -43.1 ATP (to ADP) -30.5 creatine phosphate +H,0 creatine +...
