Which of the following transport processes is involved if transport of glucose from the intestinal lumen into a small intestinal cell is inhibited by abolishing the usual $\mathrm{Na}^{+}$gradient across the cell membrane?

[II D 2 a, E 1]. In the "usual" $\mathrm{Na}^{+}$gradient, the $\left[\mathrm{Na}^{+}\right]$is higher in extracellular than in intracellular fluid (maintained by the $\mathrm{Na}^{+}-\mathrm{K}^{+}$pump). Two forms of transport are energized by this $\mathrm{Na}^{+}$gradient-cotransport and countertransport. Because glucose is moving in the same direction as $\mathrm{Na}^{+}$, one can conclude that it is cotransport.
