I want answers to question 9. I got B for question 8, but I could be wrong. For question 9 there is a typo, instead of saying "problem #9" it's suppose to say "#8" Thanks in advance!

8. The reaction below might be a suitable coupled reaction to provide the energy for which of the following reactions (A-E? Explain your choice. (3pts) Phosphocreatine + H2O creatine + Pi G":-10.3 kcal/mol A. B. C. D. E. Pyruvate + Pi phosphoenolpyruvate + H2O ADP + Pi ATP + H2O 3-phosphoglycerate + Pi 1,3-bisphosphoglycerate + H2O Malate + NAD+ oxaloacetate +NADH + H+ Glucose-1-phosphate + H2O glucose + Pi G", = +14.8 kcal/mol G", = +7.3 kcal/mol G", = +11.8 kcal/mol Go' = +7.1 kcal/mol Go,--5 kcal/mol 9. A) Using the information from problem #9, write the equation for the hydrolysis of ATP (1pt) B) Determine&G;" for the hydrolysis ofATP (see info. in problem #9) (1pt) C) The actual concentrations of ATP, ADP, and Pi differ with cell type ATP (mM) Pi (mM) 5.0 8.0 2.7 ADP (mM) as shown below. Consequently, the release of free energy with the hydrolysis of ATP will vary with cell type. Calculate the G, for the hydrolysis of ATP in muscle, liver, and brain cells (assume 25°C and express your answer to 3 sig. figs.). In which cell type is the free energy of ATP hydrolysis greatest? (4 pts) Liver Muscle Brain 3.5 8.0 0.9 0.7

Explanation / Answer

Equation of ATP hydrolysis ,. ATP+Water =ADP +P G*=RTlnK here, G* is Gibbs free energy,R is universal gas constant and T is temperature (Kelvin).K denotes for equilibrium constant. (A) G=0.82×298×ln2 is equal to 146.6kcal/mol.( B)G=0.82×298×ln0.9 is equal to minus of 25.11kcal/mol. ( C)G=0.82×298×ln0.8 is equal to minus of 53.1kcal/mol. (D)Greatest free energy is found in the muscle cell type.
