So the alpha one six glucosidase cleaves this alpha one six glycocitic bond and releases this free glucose. And that free glucose is then transformed by hexokinase to form the glucose one phosphate, which then goes on to step three, as we'll see in just in a moment. And we also form this product. 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.
