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. So let's suppose we have a high blood glucose level, and this happens after we ingest some type of carbohydrate rich meal. So when blood glucose levels are high, what happens is glucose will act as an allosteric inhibitor. It will bind onto special regulatory sites, allosteric sites.
