Simple Sugars?!
Question: How is simple sugar able to enter a cell?
Answers: How is simple sugar able to enter a cell?
Are you referring to the idea of complex sugars versus simple sugars? If so, all sugars are broken down into glucose. The 'simple sugars' are closer to the most basic and can break down much faster, but they are both sugars. Once the sugar (whichever kind) is broken down into glucose (the most basic of sugars), the non-diabetic body secretes insulin (well, technically it sends out insulin BEFORE the full breakdown because it does take a little time to react) which acts like a key to let the body move the glucose from the blood into the cells. For the person with diabetes, and a pancreas that either doesn't work as well (type 2) or doesn't work at all (type 1), the glucose can't leave the blood and never gets to the cells. That causes the body to have elevated blood-glucose levels and start to use the fat stores for energy and releasing the bad-guys, ketones, that are toxic to the system.
Was that too much info? Oops. I hope not. Let me know.
Tthe cells have certain receptors, and the glucose (simple sugar) enters through here; then the glucose is used by the cell for energy and heat and other metabolic processes.
In very simple terms, the insulin takes the glucose molecule by the hand and leads it to the cell where it (the glucose) is absorbed by the cell.
When one has type II diabetes, the glucose has difficulty in entering the cells, and hence it "hangs around" in the bloodstream, causing great havoc.
In type I diabetes the body is producing little or no insulin. Without providing insulin through injection, death can be the result.
