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. Now we want to activate this molecule and so what our body does is when there is a rise in glucose levels in our blood that causes the uptake of glucose into the liver cells. And so the cytoplasmic glucose concentration increases within the liver cells following the ingestion of the meal that is rich in carbohydrates. And these phosphorlase A molecules basically serve as glucose sensors because they're able to actually bind the glucose molecule.
