So basically, let's review what each type of our regulation method is. So earlier we spoke about allosteric regulation and this basically involves the binding of some type of specific molecule onto the allosteric site of the enzyme to either activate it or deactivate it. So we actually look at an allosteric regulation in this case. So we said a specific type of effective molecule known as cyclic adenosine monophosphate has to actually bind to the PKA molecule protein Kindness A to actually activate that. And this is our method of allosteric regulation. So proteolytic AC cleavage was discussed in this section.
