So we can summarize that in the following diagram. So let's say the glucose enters the cell, it's transformed into glucose six phosphate, then it becomes fructose six phosphate. And then the phosphor Fructase transforms it into the fructose one bits phosphate. And now we have many steps to take place and ultimately we form that pyruvate molecule. And in the presence of oxygen, the pyruvate will enter the mitochondria and it will eventually form citrate intermediate molecules. And we also form ATP molecules after glycolysis.
