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. And so what the liver cells actually do is they phosphorylate the glucose on the 6th position and they use an enzyme known as hexacinase. So hexaginase takes a phosphoryl group from ATP and places it onto carbon six of glucose and that creates glucose six phosphate. Now, once glucose actually once glucose six phosphate is created, glucose phosphate then undergoes a reaction in which there is a transfer of the phosphoryl group from the six position to the first position of that glucose and we form glucose one phosphate.
