For Reversible, we have three different cases. We have competitive, we have non competitive and non competitive incompetitive. Basically, the inhibitor resembles our substrate, and so it binds directly to the active side. And that means if we increase the concentration of our substrate while keeping the inhibitor concentration the same, we increase the ratio, and we increase the probability of this substrate binding to that active side. So we can basically displace that inhibitor from that active side. But in these two cases, our inhibitor does not actually bind to the active side because it doesn't actually resemble the structure of our substrate.
