And let's imagine that we just ingested a meal that is high in carbohydrates. And what that basically means is the blood level of glucose will essentially rise. And what will begin to happen is the beta cells of our pancreas of the eyelids of Langerhons will begin to produce insulin. And what allows those cells, the beta cells of the pancreas, to actually sense this increase in the glucose levels in the blood are these glute two protein membranes. So these transporters are typically found in the pancreas. So the beta cells of the pancreas that release the insulin, as well as the liver, and we also find them in the vasilateral membrane of things like the kidneys, as well as our intestines.
