Chapter 10: Q22P (page 319)
Endothelial cells and pericytes in the retina of the eye have different mechanisms for glucose uptake. The figure shows the rate of glucose uptake for each type of cell in the presence of increasing amounts of sodium. What do these results reveal about the glucose transporter in each cell type?
Short Answer
At the epithelial cell, there is not enough information for protein-mediated transport.
