The km also decreases. And that's because when the inhibitor actually binds onto that enzyme substrate complex to create the enzyme substrate inhibitor complex, it essentially increases the affinity of that substrate for that enzyme. Because once the inhibitor binds onto that enzyme substrate complex, that substrate cannot actually leave the active side because its affinity is higher. And if the affinity is higher, the Km value is lower. So Km will also decrease. Now, if Km decreases, the ratio one divided by a smaller Km value will become more negative.
