And so if we sum these up, this is the net equation after three steps. So after three steps of this pathway, galactose plus ATP gives us glucose one phosphate plus ADP plus H. Now, what is the final step? Because we still haven't formed a molecule that we wanted, so we wanted to form a glucose six phosphate. Well, in the last step, we basically take this glucose, we take the glucose one phosphate in step two, and we use an enzyme known as phosphor glucom mutates. Remember, a mutase is an enzyme that moves a specific type of group on a molecule to a different location on that same molecule. So all we have to do is move that phosphoryl group from position one to position six.
