And our CA MP molecule will go on to bind to a special type of protein known as our cataboli activator protein or cap. And what the cap eventually does is it will bind to site number three. But before that actually takes place, when we have a low concentration of glucose, we're going to have a high concentration of lactose. And some of that lactose will transform into another molecule known as alo lactose. And alo lactose is basically that allosteric molecule that will go on and bind to our repressor protein. And once it binds to the repressive protein, shown in red, it will inactivate that repressive protein.
