Now, the special thing about competitive inhibition is the following. For a given fixed concentration of inhibitor, if we begin to increase the concentration of that substrate, for example, we create a four to one ratio of green to purple molecules. Now, what happens is these green substrate molecules are much more likely to actually bind into that active side than compared to our purple inhibitor molecule. And that means by increasing the concentration of substrate, our substrate can basically compete and outcompete that inhibitor molecule and this is basically what defines competitive inhibition and what separates competitive inhibition from non competitive as well as non competitive. So for any given inhibitor concentration, the competitive inhibition can be reversed by increasing the concentration of substrate. That is, the substrate will begin to compete and eventually will out compete that inhibitor.
