Which one of the following is consistent with absorption of glucose molecules across the intestinal epithelium?

Glucose enters the intestinal epithelial cell through glucose channels in the apical membrane and leaves the cell through the basal membrane by facilitated diffusion.

Glucose enters the cell through the apical membrane by co-transport with Na+ and leaves the cell through the basal membrane by facilitated diffusion.

Glucose enters through the apical membrane by facilitated diffusion and leaves through the basal membrane by facilitated diffusion also.

Glucose enters the cell through the apical membrane by facilitated diffusion and leaves the cell through the basal membrane by co-transport with Na+.
