So this double reciprocal plot is a very useful way to basically determine exactly what these quantities is, what these quantities are. And these quantities can be used to basically study the way that enzymes increase the rates of different types of chemical reactions. Now, in addition to this usefulness, there is one other important application of the double reciprocal plot. We can also actually use a double reciprocal plot to basically differentiate between the three different types of reversible inhibitors. Remember, we have competitive inhibitors, we have uncompetitive and we have non competitive. And we can use the double reciprocal plot, as we'll see in just a moment, to basically differentiate between which type of inhibitor is actually present in our mixture.
