So in diagram seven we have the protein phosphatase one. And as we discussed in the previous lecture, protein phosphatase one is bound to a regulatory region and that's the region shown here. Now this molecule is in its inactive form, the PP one is in its inactive form and the reason is because it is bound to phosphorase A in the art state. So phosphorase A in the art state basically means it's in a relaxed state. And when phosphorase A is in a relaxed state, it is fully active. So phosphorase A is fully active but it's bound to this and that makes the protein phosphatase one inactive.
