Because remember, the Km value basically describes the VMAX divided by two. So when our mixture reaches a concentration of substrate that is equal to Km, the velocity of that enzyme will be exactly midway between the VMAX and the zero point. So v max divided by two, because v max doesn't change. V max divided by two doesn't change. And so if we look at the corresponding Y coordinate point, at the corresponding x coordinate point for this Y coordinate, in the case of no inhibitor, present it's here. In the case of the inhibitor, present it's farther along that x axis, and so the Km is greater.
