The equation below describes a typical unimolecular enzyme-catalyzed reaction, where E = enzyme, S = substrate, P = product, and k = rate constants. E + S ? ES ? E + P With this in mind, define the "Steady State Assumption"

6) For the reaction below; the Michaelis-Menten equation for enzyme-substrate kinetics was derived using the assumption(s) listed below: E + S ightleftharpoons ES ightleftharpoons E + P a) k_{-1} = 0 b) k_{-1} = 0, Steady-State c) k_{-2} = 0 d) k_{-2} = 0, Steady-State

For the enzymatic reaction below, derive the rate equation for product (P) formation (kobs). What is the rate-determining step? What is the predominant form of the enzyme at substrate saturation? You may apply steady-state assumption to E* and assume k1 >> k2. (4 pts)

Enzymes are often described as following the two-step mechanism: $$ \begin{aligned} \mathrm{E}+\mathrm{S} & \rightleftharpoons \mathrm{ES} \text { (fast) } \\ \mathrm{ES} &-\rightarrow \mathrm{E}+\mathrm{P} \text { (slow) } \end{aligned} $$ Where $\mathrm{E}=$ enzyme, $\mathrm{S}=$ substrate, and $\mathrm{P}=$ product. If an enzyme follows this mechanism, what rate law is expected for the reaction?
