And this is the major difference between reversible and irreversible. So Reversible basically means once we bind our enzyme or once we bind our inhibitor to the enzyme, we can easily dissociate it. And the bonding is always non covalent, but in this case, it can be covalent or non covalent, and once we bonded, we cannot dissociate it very easily. 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.
