The Michaelis-Menten rate equation for an enzyme subject to competitive inhibition is [S] max ak+[S] Beginning with the same Michaelis-Menten starting point, Vo = K?[ES] (1) a new definition of total enzyme as [E] = [E] + [ES] + [EI] (2) and the definitions of a and K? provided, derive the rate equation for competitive inhibition. Use the derivation of the Michaelis-Menten equation as a guide, developing a term for [ES]. First, develop an expression to substitute for [EI] in equation 2. Begin with the definition of the K (the Ka for binding of I to E). [E][I] [EI] Solve for [EI] and substitute the result into equation 2. (E-I) 181 5+25+ (22) E+ES+ [E] = Incorrect This substituted version of equation 2 will become equation 3 in the derivation.
