The data below are the rate of an enzyme at increasing concentration of substrate in the absence and presence of 15.0 µM of a competitive inhibitor. These experiments were performed at 25°C with 1.00 µg of enzyme having a molecular weight of 100 kD. [Substrate] vo (no inhibitor) v. (+ 15.0 µM inhibitor) in mM in µM/sec in µM/sec 1 9 3.8 2 16 7.4 5 30 16 10 55 28 25 75 50 50 85 67 100 90 80 Graph these data as a Lineweaver-Burke plot using graphing software (e.g., Excel) or graph paper. Include both lines on a single completely labeled graph. Attach your graph. Determine each of the following quantities. Expand the space below or attach extra sheets to show how you determined these values and be sure to include appropriate units. 1. $V_{max}$ 2. $K_{M}$ 3. $K_{M}^{app}$ 4. Alpha 5. $K_{i}$ For 6-10, use the data for the uninhibited enzyme. 6. $k_{cat}$ (in $s^{-1}$) 7. $k_{cat}/K_{M}$ (in $M^{-1}s^{-1}$) 8. Would you conclude this is an "efficient" enzyme? Why or why not? 9. The free energy of activation for the catalyzed reaction ($\Delta G_{cat}^{\ddagger}$) 10. If this enzyme enhanced the rate of reaction by 5 x $10^{7}$ compared to the uncatalyzed reaction, what is the free energy of activation for the uncatalyzed reaction ($\Delta G_{uncat}^{\ddagger}$)?

8. ( $ 10 \% $ ) A security camera is centered 10 meters above a 20 -meter hallway (see figure). It is easiest to desi the camera with a constant angular rate of rotation, but this results in recording the images of the surveillance area at a variable rate. So, it is desirable to design a system with a variable rate of rotation a a constant rate of movement of the scanning beam along the hallway. Find a model for the variable rate rotation when $ d x / d t=2 $ meters per second.
