And once the blood glucose levels actually rise, the liver cells will want to maintain the proper blood glucose levels. And so they will uptake some of that glucose into the liver cells. And these liver cells will take the glucose precursor molecules and begin building the glycogen. 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.
