To answer this question, please reference the Problem Solving Video: Free Energy, ATP, and Creatine in Resting Muscles. The standard free energy ( Δ G ∘ ′ ) of the creatine kinase reaction is − 12.6 kJ ⋅ mol − 1 . The Δ G value of an in vitro creatine kinase reaction is − 0.1 kJ ⋅ mol − 1 . At the start of the reaction, the concentration of ATP is 6 mM, the concentration of creatine is 12 mM, and the concentration of creatine phosphate is 25 mM.
Using the values given, calculate the starting concentration of ADP in micromolar.
ADP=. µM
creatine + ATP -----------> ADP + creatine phosphate G0 = -12.6KJ/mole
G = -0.1KJ/mole
[Creatine phosphate] = 25mM = 25*10^-3M
[Creatine] = 12mM = 12*10^-3M
[ATP] =6mM = 6*10^-3M
G = G0 + RTlnQc
-12600 = -100 + 8.314*298lnQc
-12600+100 = 8.314*298lnQc
-12500 = 2477.57lnQc
lnQc = -12500/2477.57
lnQc = -5.045
Qc = 6.44*10^-3
Qc = [Creatine phosphate][ADP]/[creatine][ATP]
6.44*10^-3 = 25*10^-3[ADP]/12*10^-3*6*10^-3
[ADP] = 6.44*10^-3*12*10^-3*6*10^-3/(25*10^-3)
[ADP] = 1.85*10^-5 M
[ADP] = 18.5*10^-6M
[ADP] = 18.5M >>>>>answer

7. Consider the reactions below and their given standard free-energy changes. Phosphocreatine ↔ creatine + P i Δ G' ° = –43.0 kJ/mol ATP ↔ ADP + P i Δ G' ° = –30.5 kJ/mol A) What is the overall Δ G' ° for the following reaction? Phosphocreatine + ADP ↔ creatine + ATP B) Explain how phosphocreatine can be used as a kind of mechanism to STORE excess ATP during periods of rest. Why might this be necessary?
We have seen all term that cells use the hydrolysis of high energy phosphate from ATP to make metabolic reactions thermodynamically favorable. Whereas most enzymes that utilize ATP hydrolyze between the b and g phosphates (yielding ADP + Pi), some enzymes hydrolyze ATP between the a and b phosphates (yielding AMP and PPi). ∆G°’ of phosphate hydrolysis is -31 kJ/mol for ATP + H2O --> ADP + Pi, and ∆G°’ of phosphate hydrolysis is -46.5 kJ/mol for ATP + H2O...

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.
