And if we graph the relationship between the rate at which we produce this product molecule, the ncarbon oil as pertain with respect to the concentration of the substrate, the aspartate, as shown in this diagram, we're going to see not the typical Michaela SmithIn curve, but we're going to see the sigmoidal s shape curve. And that's because this enzyme and allosteric enzymes in general, observe cooperative behavior. Now, what do we mean by cooperative behavior? So, let's think back to hemoglobin. So, when we discussed hemoglobin, we discussed what it means for an enzyme or a protein to behave in a cooperative fashion. So, in our discussion on hemoglobin, we said that hemoglobin behaves cooperatively because it consists of different subunits.
