It's actually somewhere in between. And so what that means is our body has to couple this reaction with the reaction that is product favored. And that's exactly where the second reaction comes into play. 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.
