Not all enzyme inhibitors play by the same rules. Competitive inhibitors fight for the active site and lose when substrate floods in. Non-competitive inhibitors bind somewhere else, warp the enzyme's shape, and can't be outcompeted no matter how much substrate you add. Tap the buttons to switch between inhibitor types and watch what happens.
Competitive inhibitors are structurally similar to the natural substrate. They dock into the active site and physically block it. When substrate concentration increases, substrate molecules start winning the competition for binding sites through sheer numbers — it's a statistical game. At very high substrate levels, the inhibitor can be almost completely displaced. This is why competitive inhibition is reversible and concentration-dependent. The inhibitor hasn't changed the enzyme; it's just occupying space that substrate wants.
Competitive inhibitors bind the active site and can be outcompeted by raising substrate concentration, while non-competitive inhibitors bind an allosteric site, deform the enzyme, and cannot be overcome with more substrate.
