The pyrophosphate here in the presence of water will actually be hydrolyzed into two orthophosphate molecules. And this reaction is very much product favorite. And so because this reaction takes place towards the product side, we continually use up the pyrophosphate. And that drives this entire reaction towards this side. And that's exactly what allows this reaction to actually take place in the first place. And if we sum up these two reactions, this will be the net reaction for activating the glucose.
