The graph below shows two curves obtained from an enzyme reaction, either in the presence or absence of substance X. Substance X is: with X without X [S] 1. an activator of the enzyme and lowers Km. 2. an activator of the enzyme and raises Km. 3. X is an inhibitor of the enzyme and raises Km and lowers Vmax. 4. an inhibitor of the enzyme and lowers Km. 5. an activator of the enzyme and lowers Km and raises Vmax.

The graph shows three plots of velocity (v0) versus substrate concentration ([S]). Determine which curve represents an enzyme's reaction velocity without any inhibitor present, which curve represents the velocity in the presence of a mixed inhibitor, and which curve represents the velocity in the presence of a competitive inhibitor. Use data from the plots of v0 versus [S] without an inhibitor and in the presence of a competitive inhibitor to calculate Ki when 2.0 ÎĽM of the inhibitor is present.

The following kinetic data (see below) were obtained for an enzyme in the absence of any inhibitor (1), and in the presence of an inhibitor (2). Assume the total enzyme concentration is the same in each experiment. [S] (mM) (1) Uninhibited vo (mM/s) (2) Inhibited vo (mM/s) 1 3.8 2.2 2 7.3 4.3 4 13.3 8.2 8 22.9 14.9 12 30.0 20.4 Draw the Lineweaver-Burk plot for both reactions. Label the axes properly and please draw the plots to size as you will use them to determine kinetic parameters. Determine Vmax for the uninhibited enzyme. Vmax_______________________ c) Determine the inhibitor type for the inhibited curve (2) _______________________________

The following kinetic data were obtained for an enzyme in the absence of any inhibitor $(1),$ and in the presence of two different inhibitors (2) and (3) at $5 \mathrm{m} M$ concentration. Assume $\left[\mathrm{E}_{T}\right]$ is the same in each experiment. $$\begin{array}{cccc} & (1) & (2) & (3) \\ {[\mathrm{S}]} & v(\mu \mathrm{mol} / & v(\mu \mathrm{mol} /) & v(\mu \mathrm{mol} /) \\ (\mathrm{m} M) & \mathrm{mL} \cdot \mathrm{sec}) & \mathrm{mL} \cdot \mathrm{sec}) & \mathrm{mL} \cdot \mathrm{sec} \\ 1 & 12 & 4.3 & 5.5 \\ 2 & 20 & 8 & 9 \\ 4 & 29 & 14 & 13 \\ 8 & 35 & 21 & 16 \\ 12 & 40 & 26 & 18 \end{array}$$ Graph these data as Lineweaver-Burk plots and use your graph to find answers to a. and b. a. Determine $V_{\max }$ and $K_{m}$ for the enzyme. b. Determine the type of inhibition and the $K_{1}$ for each inhibitor.
