1. AG" for ATP hydrolysis is -30.5 kJ/mol. Calculate AG in kJ/mol for this reaction in a liver cell, if there are 4.0 mM ATP, 1.35 mM ADP, and 4.65 mM Pi. Assume 37 degrees Celsius, pH=7, R= 8.314 J/mol x K Disregard H* generation. 2. Explain why AG and AG differ? The standard reduction potential at 25°C for the Cu2+/Cu redox couple is +0.34 V, and the standard reduction potential at 25°C for the Zn2+/Zn redox couple is -0.76 V.Faraday's constant is 96,485 J/V:mol. 1. If we were to combine the two redox couples, which substances will get oxidized and which reduced? Which is the oxidizing agent and which is the reducing agent? Write the resulting reaction. 2. Calculate the standard reduction potential difference 3. Calculate the standard free energy change for the above reaction. Comment on whether the reaction will proceed spontaneously as written above in question 1
