4.5 co-transport and absorption of glucose in the ileum Flashcards
1
Q
how does the ileum increase the rate of movement across the membrane?
A
- microvilli
- villi
- constant blood supply
2
Q
co-transport of amino acids/ glucose
A
- sodium ions are actively transported out of epithelial cell into the blood
- maintains a concentration gradient into the cell
- sodium ions diffuse into cell by facilitated diffusion
- carries glucose/ amino acids with it which goes against its concentration gradient
- glucose/ amino acids are move out by facilitated diffusion into the blood
