This graph shows a decrease in enzyme activity with increasing substrate concentration, indicating that an inhibitor is present. The fact that the curve levels off at high substrate concentrations suggests that the inhibition is noncompetitive, meaning that the inhibitor binds to a site on the enzyme that is distinct from the active site and alters the enzyme's conformation so that it is less active.
