Now, in other tissues, in other cells of our body, in non liver cells, there's a simpler pathway that is followed. So if we recall stage one of glycolysis, in stage one we actually form fructose six phosphate in step number two. And in step number three of stage one, we basically transform that fructose six phosphate into fructose one six bisphosphate. So the simplest step is to actually take that fructose, use an ATP molecule and a special enzyme we call Hexokinase, which was also actually used in stage one of glycolysis. And we formed fructose six phosphate. And fructose six phosphate can be fed directly into that glycolytic path into stage one.
