Unfortunately, the publisher printed some of the formulas in the Appendix on page 261 with errors. The correct equations are given here.

$$\frac{\hbox{dGln}}{\hbox{d}t}=\frac{F_2}{V}\hbox{Gln}_{\rm in}-\frac{(F_1+F_2)}{V}\hbox{Gln}-q_{\rm {gln}}X_{V}$$
$$\frac{\hbox{dLac}}{\hbox{d}t}=q_{\rm {lac}}X_V-\frac{(F_1+F_2)}{V}\hbox{Lac}$$
