### Enzymatic Activity with Compounds X and Z This table examines how two compounds, X and Z, influence an enzyme's catalytic activity. These compounds are known to bind to the enzyme, but not at the active site. #### Table: Effect of Compounds X and Z on Enzyme Activity | Substrate Concentration (mM) | Rate of Enzyme-Catalyzed Reaction | |------------------------------|-----------------------------------| | | No Addition | + Compound X | + Compound Z | | 0 | 0 | 0 | 0 | | 10 | 50 | 60 | 10 | | 20 | 90 | 105 | 20 | | 30 | 110 | 115 | 28 | | 40 | 115 | 116 | 35 | **Analysis of the Data:** - **Without any addition**, the rate of the enzyme-catalyzed reaction increases with substrate concentration, demonstrating typical enzyme kinetics. - **With Compound X**, the reaction rate is slightly elevated compared to no addition at each concentration level, suggesting that Compound X enhances the enzyme's activity. - **With Compound Z**, the reaction rate is significantly lower than that with no addition, indicating that Compound Z reduces the enzyme's activity. This data highlights how different compounds, even when not binding at the active site, can alter enzyme activity.
