Problem

Carboxylation of pyruvate to oxaloacetate is endergonic with

\Delta G^{\circ}=+32\,\text{kJ}\,\text{mol}^{-1}

and proceeds in cells by coupling to the hydrolysis of one ATP per reaction. If a cell has

5.0\,\text{mmol}

of ATP available, what is the maximum amount of oxaloacetate (in mmol) that can be produced under standard conditions? (a)

4.8

(b)

5.0

(c)

2.5

(d)

7.9
