And so now we move on to this particular state. So this is bound and by binding it basically creates some type of change that increases the affinity of this pocket for lactose or some other type of sugar. So the lactose, which is a disaccharide by the way, moves into the pocket. And once it moves into the pocket, as shown here, it basically creates overall conformational change that inverts the entire structure of that particular membrane protein. And so now, instead of pointing this way, it inverts. And this inversion, by the way, is also known as an eversion.
