Under saturation conditions, an enzyme-catalyzed reaction had a velocity V . Which of the following would increase the rate of the reaction?

Question

Quizplus · Accepted Answer

Under saturation conditions, the enzyme's active sites are fully occupied by the substrate, meaning that increasing the substrate concentration further (B) will not increase the reaction rate. Decreasing the substrate concentration (A) or enzyme concentration (C) would likely decrease the reaction rate. Increasing the enzyme concentration (D), however, provides more active sites for the substrate to bind to, potentially increasing the reaction rate if other conditions are favorable.
