And that's exactly why the Y intercept is higher for the purple curve than that red curve. Now, what happens to the Km? Well, the Km is also affected. 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.
