And what that means is they not only use the glycolysis to produce ATP molecules that the liver cells actually need to survive, but the liver also has to do things like maintain the glucose levels in our blood. If the levels are too high, uptake that glucose and transform it into glycogen. If the levels are too low, break down that glycogen and release the glucose into our bloodstream so that the other cells of our body can essentially use that glucose to form ATP molecules. And it has many, many other roles. For instance, it uses the glycolysis process to basically synthesize building blocks like fatty acids as well as amino acids and so forth. So liver cells have many different types of functions.
