So these are the two important reasons for why we have the glucokinase in these liver cells. And finally, let's move on to pyruvate kinase. So pyruvate kinase is responsible for catalyzing the final step of glycolysis and that means the transformation of phosphorino Pyruvate into Pyruvate and ATP. So this is our step. So we begin with glucose that is eventually transformed to fructose one six bisphosphate this molecule here, so many more steps take place. Then we have PEPSO phosphate, enochyruvate and the pyruvate kinase transforms this molecule into Pyruvate and ATP.
