Now, once we continually add these glucose molecules, eventually we want to actually branch that glycogen. And so that's where step six takes place. Glycogen branching enzyme is responsible for creating those alpha one six linkages which lead to the branching points. And for this process to actually continually taking place, we have to take the UDP that we form here and regenerate back that UTP. And that's where step seven comes into play. The enzyme nucleotide di nucleoside diphosphokinase uses an ATP to attach it onto the UDP here, and that forms that UTP.
