Glucose absorption from the ileum lumen into the bloodstream involves co-transport with sodium ions, facilitated by the sodium-potassium pump, followed by facilitated diffusion of glucose into the blood.
Glucose is absorbed into the bloodstream from the ileum lumen through co-transport with sodium ions, driven by a sodium-potassium pump. Glucose then moves into the blood down its concentration gradient via facilitated diffusion.
| Front | How is glucose absorbed into bloodstream from lumen of ileum |
|---|---|
| Back | 1. Sodium ions actively transported from epithelial cell to blood, this creates a concentration gradient. This process occurs with the help of a sodium-potassium pump 2. Sodium and glucose can move into the epithelial via lumen through cotransport. Glucose uses the concentration gradient of sodium to move into the epithelial. 3. Glucose diffuses into the blood down a concentration gradient through facilitated diffusion |
