Now notice that first of all, it's lower than the five than the normal amount in our blood. And before we discuss what that actually means, let's remember what a Km value actually tells us. So the Km is simply the Mikhailus constant and the Km value basically tells us the concentration at which exactly half of the active size of that particular enzyme are actually filled. And that gives us the velocity value that is exactly half of the maximum velocity value. And because the Km value is much lower than the five millimolar value, what that means is these are very effective at binding those glucose molecules and transporting those glucose molecules across the cell. So because of the low Km values of these two glucose transporters, we see that when we have a five millimolar concentration of blood glucose, which is the normal one.
