Chapter 10, Problem 86E

One reaction that occurs in human metabolism is

For this reaction $\Delta G\text{° =14 kJ}$ at 25°C.
a. Calculate K for this reaction at 25°C.
b. In a living cell this reaction is coupled with thehydrolysis of ATP. (See Exercise 84.) Calculate $\Delta G°$ and K at 25°C for the following reaction:
$\begin{array}{l}\text{Glutamic acid(}aq\text{)+ATP(}aq{\text{)+NH}}_{\text{3}}\text{(}aq\text{)}\hfill \\ \rightleftharpoons \text{Glutamine(}aq\text{)+ADP(}aq{\text{)+H}}_{\text{2}}{\text{PO}}_{\text{4}}{}^{\text{–}}\text{(}aq\text{)}\hfill \end{array}$
