1. Derivation of a rate expression for two consecutive reactions
reaction sequence:
k₁
k₂
[ES] ₁
K-1
K-2
where substrate S binds with enzyme E to form complex [ES]₁. Complex [ES]₁ then transforms into
complex [ES]2. Complex [ES]2 then transforms into product(s) P and free enzyme E.
Develop a suitable rate expression for the product P formation [r = k5 [ES]2] by using:
a. the quasi-equilibrium (Michaelis-Menten) approach
Show all of your algebraic steps for the M-M method. Assume that you can define the following reaction
parameters:
K'M = 1/(K₁ * K₂)
VMAX = K3 * [E] total
Where K₁, K₂ are the equilibrium constants for reaction steps 1 and 2 in the mechanism above.
S+ E
[ES] 2
: Consider the following
k3
→ P+E
