In the frog muscle rectus abdominis, the concentrations of ATP, ADP and phosphate are 1.25×10-3 M, 0.50×10-3 M, and 2.5×10-3 M, respectively. Under standard biological condition, the Gibbs free energy change ∆r Go ' for the hydrolysis of ATP is -31.0 kJ mol-1.    ATP + H2O → ADP + phosphate   a. Calculate the Gibbs free energy change ∆r G' for the hydrolysis of ATP in the frog muscle as described. T=298.15 K and pH=7.0. Write your answer with proper sign, significant digits and unit [ ]   b. If the ATP concentration is maintained at 1.25×10-3 M, and the phosphate concentration is maintained at 2.5×10-3 M, what would be the theoretical (may not exist) equilibrium concentration of ADP in the muscle (T=298.15 K and pH=7.0)? Write your answer with proper sign, significant digits and unit [ ]

Question

 

In the frog muscle rectus abdominis, the concentrations of ATP, ADP and phosphate are
1.25×10-3 M, 0.50×10-3 M, and 2.5×10-3 M, respectively. Under standard biological condition, the Gibbs free energy change ∆r Go ' for the hydrolysis of ATP is -31.0 kJ mol-1.
  
ATP + H2O → ADP + phosphate
 
a. Calculate the Gibbs free energy change ∆r G' for the hydrolysis of ATP in the frog muscle as
described. T=298.15 K and pH=7.0.
Write your answer with proper sign, significant digits and unit [ ]
 
b. If the ATP concentration is maintained at 1.25×10-3 M, and the phosphate concentration is maintained at 2.5×10-3 M, what would be the theoretical (may not exist) equilibrium
concentration of ADP in the muscle (T=298.15 K and pH=7.0)?
Write your answer with proper sign, significant digits and unit [ ]
