Figure 15. 5 structure of the gi wall. Lactose intolerance: this is the norm no mammals besides human beings that drink milk. Epithelial cells have the disaccharide-ases (lactase, sucrase, and maltose) active site is in the lumen. Form monomers at the same spot you"re going to absorb them on the epithelial cell do this by transporting them with na+ Must get across some membranes and insulin is required to express the. Glut they need to get across the membrane (*brain is the only membrane that doesn"t require insulin) When glucose enters the blood, it directly activates insulin from the. When insulin comes to the cell and binds its receptor, it activates signaling pathways causing the movement of vesicles inside to the cell to docking sites on the cell membrane. **this cell in the absence of insulin when sugar levels are low is not getting any glucose (because it just gave up its gluts)
