The kinetic data given below are for an enzyme in the absence and presence of a reversible inhibitor. From the data, generate both a Michaelis-Menten and Linweaver-Burk Plot for both that uninbibited and inhibited reactions. Graph both the uninhibited and inhibited data on the same plot. From these data calculate the Vmax and Km for the enzyme in absence and presence of the inhibitor. Is the inhibitor working cometitively or noncompetitively? Explain. [S], mM Vo, mM/min Vo, mM, min with...

An enzyme-catalyzed reaction to the presence of 5 nM of reversible inhibitor yields a Vmax value that is 80% of the value in absence of the inhibitor. The KMvalue is unchanged. a) what type of inhibition is occurring? b) what proportion of the enzyme molecule will have bound inhibitor? c) Draw the Lineweaver-Burk (known as double-reciprocal plot) for uninhibited and inhibited reaction.
