Chapter 23, Problem 46QAP

Glycolysis is the process by which glucose is metabolized to lactic acid according to the equation
${\text{C}}_6{\text{H}}_{12}{\text{O}}_6\left(aq\right)\to 2{\text{C}}_3{\text{H}}_6{\text{O}}_3\left(aq\right)$
$\Delta G°=-198$ kJ at pH 7.0 and 25°C
Glycolysis is the source of energy in human red blood cells. In these cells, the concentration of glucose is $5.0\times {10}^{-3}$ M, while that of lactic acid is
$2.9\times {10}^{-3}$ M. Calculate AG for glycolysis in human blood cells under these conditions. Use the equation $\Delta G=\Delta G°+\text{RT}$ In Q, where Q is the concentration quotient, analogous to K.
