So it's an exergonic reaction. That's because the ATP is broken down into a more stable molecule and that drives this exergonic reaction. Now, the point of this step is to one destabilize the glucose to make it more reactive and begin preparing it for stage two. And the second point is, by adding this polar component, we trap that glucose in a cell, it will not be able to exit that cell because one, it can't pass the membrane and B, it cannot use any of those transport membrane proteins because its structure is different. Now let's move on to step two. In step two, the goal is to basically take that glucose phosphate and transform it into an isomer, into fructose six phosphate.
