So let's take a look at the following diagram. So, this diagram describes the fully active r state of phosphorace A found in the liver, and the T state, inactive state. Office Fourlase A of the liver. So essentially, when glucose molecules bind into a specific allosteric regulating side shown here and here, what we have is a transition from the R state, the fully active state, where the activity of the enzyme is high, to the inactive state, the T state, where the activity of the enzyme is low. Now, we can have two different situations. We can basically have a situation in which the blood glucose levels are low, or we can have a situation where the glucose blood level is high.
