In fact, when the majority of the cells take in that non glucose molecule, they normally convert, transform the non glucose into glucose. And this takes place in liver cells as well as intestinal cells in our intestines, in the liver, in our body. Now, glucose can be broken down and transformed into ATP molecules and ATP is used for energy. Now, in the process of glycolysis, we basically use glucose to form ATP as well as Pyruvate molecules and don't. And then those Pyruvate molecules are used in the creep cycle to form even more ATP molecules, the energy molecules that are used by the cell. Now, when our cell basically contains ample amounts, so enough ATP and it doesn't need to form any more ATP, it can basically take the glucose and store glucose in a polymer form known as glycogen.
