Now, notice that when we go from this molecule to this molecule, we essentially remove the branching points. We basically transform the branched polymer of glycogen to a linear polymer of glycogen. And now this only contains the alpha 114 glycosytic bonds that can be cleaved by glycogen phosphorase. And so once we form this linear glycogen in step two, the glycogen phosphorase moves on to this glycogen and begins breaking these alpha one four glycocitic bonds and those glucose one phosphate molecules produce, then go on to step three. And so let's move on to step three and let's see what happens in step three. Now in step three, we basically transform the glucose one phosphate into glucose six phosphate.
