Well, glucose can easily leave that cell, but glucosex phosphate is trapped within the cell. And so glucosex phosphate cannot actually escape the cell. And glucosex phosphate can then be easily transformed into glycogen. And so if the cell wants to form the glycogen, why would it want to basically go on to form the glucose and then because then it would have to go on to reform that glucose six phosphate. So in the majority of the cells of our muscle, like skeleton muscle cells, this step doesn't actually take place for two reasons. Number one, we want to basically make sure that glucose doesn't leave the cell.
