Now, in the lectures to come, we're going to discuss glycogen metabolism and we can break down glycogen metabolism into subcategories. So we have the degradation of glycogen, so the breakdown of glycogen, and we also have the synthesis of glycogen. Now, if we examine the breakdown of glycogen, the degradation of glycogen, we can actually categorize that process into three different steps. So we have the release of glucose one six phosphate from glycogen. So we actually take the glycogen that contains, let's say, n number of glucose molecules and we release a single glucose one phosphate and we basically form a modified glucose, a modified glycogen that now contains N minus one glucose monomers. Now, once we form this glycogen that contains one less glucose molecule, we actually have to remodel, we have to restructure that glycogen so that we can further break down that glycogen and release many more glucose one six phosphate molecules.
