Consider a description of an enzymatic reaction pathway that begins with the binding of substrate S to enzyme E and ends with the release of product P from the enzyme. E+S →ES → EP E+P Under many circumstances, KM = [E] [S] / [ES] What proportion of enzyme molecules are bound to substrate when [S] = KM? Why? Recall that when [S] = KM, the reaction rate is Vmax/2. Does your answer to Part A make sense in light of...
5) The reaction, 2A + B P (P is the product). proceeds via a rapid pre-equilibrium (with equilibrium constant, K) followed by a slow rate determining step (with rate constant, kz) as shown below: 2A к = Az (fast pre-equilibrium) A2+B Products (slow) Develop an expression for the rate of formation of products as a function of [A], [B], K, and kz 6) The reaction, A+B+C - P(P is the product) proceeds by the following mechanism. k, A+B=0 I+CP "T"...

2. In a single substrate enzyme-catalyzed reaction, the forward rate constant (formation of ES) is 2.1x105 M-1 s-1 , the reverse rate constant (dissociation of ES to E +S) is 9.4x103 s-1 , and the catalytic rate constant (turnover of ES to P) is 7.2x102 s-1 . From this data, KM is:
Enzymes are often described as following a two-step mechanism: Where E = enzyme, S = substrate, ES = enzyme-substrate complex, and P = product. Write the balanced equation for the overall reaction. Identify and intermediates in the reaction mechanism. Derive an expression for the rate law.

The Michaelis-Menten equation models the hyperbolic relationship between [S] and the initial reaction rate V for an enzyme-catalyzed, single-substrate reaction E+S E S E+P. The model can be more readily understood when comparing three conditions: (S) <<K.. [S] = Km, and [S] >> Km. Match each statement with the condition that it describes. Note that "rate" refers to initial velocity V, where steady state conditions are assumed. Etotal) refers to the total enzyme concentration and Etree refers to the concentration...
