So this process, step one of glycogen breakdown, proceeds toward the right side, toward the product side. Because the cell contains a higher concentration of orthophosphate compared to glucose one phosphate, and because the formation of glucose one phosphate bypasses the usage of the ATP, it forms directly the glucose one phosphate from that glucose. And this is in fact energetically favorable. Now let's move on to step number two. So in step number two, what we ultimately want to do is, oh, and by the way, the glucose one phosphate that we form as a product in step one will actually be used in step three. But the glycogen and minus one is actually used in step two.
