So we can easily dissolve inside our blood, just like glucagon can. And insulin also binds onto the cell membrane of our target cells, the liver cells or the muscle cells. And it basically stimulates the opposite process that we discussed earlier. Now, what happens is, because we have plenty of glucose and amino acids floating around inside our bloodstream, what insulin does is it causes the cell membrane to become more permeable to amino acids and to glucose. And now glucose and amino acids go into our cells, into liver cells and muscle cells. And those cells basically use the amino acids to form protein and they use the glucose to form our glycogen.
