And so if we have a high citrate concentration in the cytoplasm, that citrate will go on and buy until phosphorptokinase and it will basically increase the ability of the ATP to actually inhibit the phosphorptokinase. And so just like ATP, citrate is also an allosteric inhibitor to the phosphorptokinase. And this is the second important difference between the phosphorptokinase in skeletal muscle cells and the one in liver cells. 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.
