So we have 1234-5678, 910, eleven. So this is how glycogen is actually branched. And once we undergo this entire process, for this process to actually continue taking place, we have to regenerate the UTP molecules, the urine triphosphate that we use up in this particular step, because glycogen will essentially stop taking place if we don't have enough UTP, because we need the UTP to actually generate the UDP glucose, the active form of glucose. And so in the final step, what our cells actually do is they use an ATP molecule, transfer the phosphoral group from ATP onto the UDP that we basically formed in this step here. So we take the UDP, we take an ATP and we transfer that phosphorus loop onto this to basically reform the UTP that now can be used in this step to continually produce the UDP glucose molecules needed to generate that glycogen. And the enzyme that catalyzed this step is nucleocide difosphokinase.
