Name: Quiz 6: Take home quiz. You may use your notes and the textbook. If you work with someone else, make sure you understand the solution (don't just simply copy someone else's work). TWO SIDED! Answer questions 1-3 below based the hydrolysis reactions given below: Glucose-1-phosphate Hizo glucose PAG 20.9 kl/mol. ATP Hzo glucose +P AG -30.5 kl/mol Constants: R 8.3145 J/mol K Equations: AG AG RTIna AG -RTInkea 1. (2 points) Calculate the equilibrium constant for the hydrolysis of glucose-1-phosphate 37°C. at 2. (2 points) calculate the AG (in kl/mo) for the hydrolysis of glucose-1-phosphate at 37cifthe concentration of Glucose-1-phosphate is 3.0 mM, glucose is 0.8 mM and Pi is 4.0 mM. Assume the concentration of water remains the same (don't include water in your equilibrium expression) 3. (3 points) A. Assume that reactants and products are present in equimolar amounts. Draw an arrow in the direction the reaction will progress (ie or glucose-1-phosphate ADP Glucose ATP b. Determine the AG (in ku/mo) for the reaction in part a.

Explanation / Answer

1. We know that

G°=-2.303RTlogK

For hydrolysis of glucose-1-phosphate G°=-20.9Kj/mol, T=298k

Given R=8.314J/mol-K

G°=-20900=-2.303×298×8.314×logK

logK=3.663

K=4.6×103
