And that's exactly why in stage two we can now break down this unstable molecule as we'll see in just a moment. Now, step three is actually very important stage one because it's our committing step. So once we undergo step three, our glucose molecule actually commits to our glycolysis pathway. So for example, if we move back to this molecule, the glucose six phosphate, the glucose six phosphate does not necessarily have to actually go on to produce the fructose 116 biphosphate. If we have plenty amounts of energy inside the cell, the glucose six phosphate can then be stored as glycogen. Now, if we don't have that much energy in a cell, then the glucose six phosphate will go on to form the fructose six phosphate, which will go on to form the fructose one six biphosphate.
