Question:
The equation for ATP hydrolysis is
ATP yields ADP + Pi delta G*= -30.5 kJ/mol
( H20)
(a) Calculate ?G for ATP hydrolysis to rank the following conditions from most favorable to least favorable. Assume a temperature of 37.0 ?C. R = 8.315 J/(mol?K).
ATP Hydrolysis most favorable
ATP hydroysis least favorable
The choices are:
muscle: [ATP]= 8.1mM; [ADP]= 0.9mM [Pi]= 8.1mM
brain: [ATP]= 2.6mM; [ADP]= 0.7mM [Pi]= 2.7mM
liver: [ATP]= 3.4mM; [ADP]= 1.3mM [Pi]= 4.8mM
(b) Calculate ?G for ATP hydrolysis in muscle at 18 ?C. Use the muscle concentrations from part a.
Delta g = kJ/mol
