And they will store the glycogen in tiny granules found in the cytoplasm of liver cells. Now, what exactly is the process by which we synthesize glycogen in liver cells and skeleton muscle cells? Well, that's what we're going to focus briefly in this lecture and the next lecture. Now, in the same analogous way that gluconeogenesis, the building of glucose molecules and glycolysis the breaking down of glucose molecules, in the same analogous way that these two processes are not simply the reverse of one another, we see that glycogen synthesis is not simply the reverse of the breakdown of glycogen. In fact, as we'll see in this lecture, glycogen synthesis actually follows a completely different reaction pathway when it uses the glucose precursors to actually build the glycogen polysaccharide. Now, there are two important processes that we have to consider when actually building the glycogen.
