How does the shape of a competitive enzyme inhibitor determine its mechanism of inhibition? The inhibitor and substrate have different shapes. An allosteric site on the enzyme binds to the inhibitor, which prevents the active site from binding with the substrate. The inhibitor and substrate are similar in shape. The active site of the enzyme binds to both the inhibitor and the substrate, inactivating the enzyme. The inhibitor and substrate have different shapes. The active site of the enzyme binds to both the inhibitor and the substrate, inactivating the enzyme. The inhibitor and substrate are similar in shape. The active site of the enzyme binds to the inhibitor instead of the substrate.
