    The lock-and-key analogy for the most part works, but it’s an incomplete explanation. Cells use secondary transport systems to ferry hormones from the outside into the inside of the cell to be used. Once the cell has enough glucose, a feedback occurs so that the process stops. Then the insulin takes any remaining glucose in the blood stream and stores it as fat. If anything, insulin is more like a knock on the door, and then the secondary transport system opens it and then closes it again.

    However, I would definitely disagree with Wil that cells are a revolving door. Cell membranes are permeable, but only when activated properly. The entire idea of the cell membrane is to keep it protected from bacteria, viruses, other hormones or material that it doesn’t mean. Cell membranes don’t just let anything in without the proper, say, password. (Oh dear, another analogy!)

    I think I’ll stop here. :)

    I use Diabetes Mall’s logbooks because I like to graph.

    Other analogy: LADA is like the Russian car. It runs, sort of, but not like a Maserati, and it needs help to go any place at all. Sometimes it just sits at the curb and I might be better off walking. But is car. Is my car. Is OK.
