Now, let's move on. And one last thing I want to mention. Basically, in our competitive inhibition, we saw that by increasing our concentration of the substrate, we can basically kick out our inhibitor from the active side. Now, for this particular case, because the inhibitor does not actually bind to the active side, no matter how much we increase the substrate concentration by, that will basically not kick off our inhibitor. So that's the major difference between competitive inhibition and these two types of inhibition. Now, what exactly is Irreversible inhibition?
