Well, the skeleton muscle cells actually will allow us to move to that table and grab that sandwich. And it's the brain cells in our nervous system that essentially will tell those skeleton muscles to make our way to that table so that we can actually eat that sandwich and survive. So what I'm basically saying is, under certain circumstances, when the blood glucose level is low, the fact that in liver cells we have the glucokinase basically means the glucokinase will be much less likely to bind to that glucose than the hexokinases found in the brain cells and the muscle cells. And so, when the blood glucose level is low, the low affinity of the glucokinase for glucose, remember, glucokinase is 50 times less likely to bind to glucose than hexaginase is found in other cells. So muscle cells and brain cells. And so that basically ensures that the hexokinases of the brain and the muscle cells get that glucose first, because under these conditions of, let's say, starvation, the liver function isn't as important as the muscle function and the brain function that will allow us to actually get to that food source and ingest those carbohydrates, those sugar molecules.
