And the ADP will not be able to transfer that phosphoral group. And so that's why this is a very important step. Now let's move on to step number two. We call the isomerization step. So once we actually form that glucose, a glucose six phosphate, so glucose that contains a phosphoryl group on carbon number six, the next step is to actually transform that glucose into a fructose. And to transform it into a fructose, what must happen first is it actually has to open up into its open chain.
