5 Questions
Where does the process of transcellular transport of glucose across an intestinal epithelial cell primarily occur?
Apical domain of the plasma membrane
What is the primary driving force for the movement of glucose into the intestinal epithelial cell?
Symport with Na+
Which protein maintains the Na+ gradient driving the glucose symport across the intestinal epithelial cell?
Na+-K+ ATPase
In which membrane domains of the intestinal epithelial cell does facilitated diffusion of glucose take place?
Basal and lateral
What is the role of the glucose carrier protein in the transcellular transport of glucose across the intestinal epithelial cell?
Mediating facilitated diffusion of glucose out of the cell
Explore the process of glucose transcellular transport across intestinal epithelial cells, involving the asymmetrical distribution of transport proteins in the plasma membrane. Learn how glucose moves from the gut lumen to the extracellular fluid and eventually into the blood.
