Epithelial Cell Blood Co Transport Na  From Concentration Gradient

Front Describe the absorption of glucose/amino acids by co-transport in the ileum.
Back
- sodium potassium ATPase actively transports 3 Na+ from epithelial cell into blood
- and 2 K+ from blood into epithelial cell 
- maintains concentration gradient allowing

- Na+ ions to diffuse by facilitated diffusion from intestinal lumen into epithelial cell
- provide energy for co-transport of glucose against concentration gradient using the same carrier protein

- glucose diffuses by facilitated diffusion from epithelial cell into blood
