glycogenesis is the synthesis of glycogen molecules from glucose precursors. So let's suppose we just ingested a meal that is rich in sugar molecules. And so what that means is inside our blood plasma there will be an increase in the glucose levels. Now, our liver is responsible for maintaining the proper glucose levels of our of blood. And so what the liver cells do is they begin to uptake some of that glucose into the cytoplasm of that cell. Now, once the glucose is inside the cell, the liver cell will want to trap that glucose inside the cell and prevent it from actually escaping back into the blood plasma.
