Quizplus · Accepted Answer

The graph shows a sigmoidal curve, indicating a mixed noncompetitively inhibited reaction. The initial rate of the reaction is slow, followed by a rapid increase in the rate before reaching a plateau. This is typical of a mixed noncompetitively inhibited reaction, where inhibition occurs at both the substrate and enzyme binding sites.
