So let's say this is the inside of the cell, this is the outside and now it opens from the outside and once it opens that molecule the substrate molecule can leave that cell and exit that cell. So we see the ultimate result of this particular mechanism is the same exact result that we saw in the ptype Atpas. That is, we move these molecules across the membrane against their electrochemical gradient. Now, the final step in this process is these two ATP molecules are actually hydrolyzed by using two water molecules. So we have two water molecules, not one. We basically use two water molecules to hydrolyze each one of these ATP molecules and that produces and releases two ATP molecules and two phosphate molecules as shown here.
