WebbCompetitive Inhibitors. These are structurally similar to the substrate of the enzyme and bind to the active site. This means that when a competitive inhibitor binds to the active site of an enzyme, it prevents the substrate from binding to the active site. Only once the inhibitor has been released from the active site can the substrate bind. Webb19 sep. 2024 · Thus enzyme inhibition becomes stronger and maximum velocity cannot be reached.
