The Michaelis‑Menten equation models the hyperbolic relationship between [S] and the initial reaction rate V 0 V0 for an enzyme‑
catalyzed, single‑substrate reaction E + S − ⇀ ↽ − ES ⟶ E + P E+S↽−−⇀ES⟶E+P . The model can be more readily understood when comparing three conditions:
[ S ] < [ S ]>>Km
[ S ] = K m
Match each statement with the condition that it describes. Note that "rate" refers to initial velocity V 0 where steady state conditions are assumed. [ E total ] refers to the total enzyme concentration and [Efree] refers to the concentration of free enzyme.
1. [ S ] < 2. [ S ]>>Km
3. [ S ] = K m
4. Not true for any of these conditions.
A. [Efree] is about equal to [Etotal]
B. Half of the active sites are filled with S.
C. [ES] is much lower than [Efree]
D. Almost all active sites will be filled.
E. Increasing [Etotal] will lower Km.
F. Reaction rate is independent of [S]

1 answer:
Answer:
The equation formulated by Michaelis-Menten is expressed as
v₀ = Kcat × [E₀] × [S] / (Km + [S])
in which,
Kcat denotes the experimental reaction rate constant; [S] signifies the concentration of the substrate, and
Km represents the Michaelis-Menten constant.

The enthalpy change associated with the precipitation reaction is 84 kJ/mole
Why?
The chemical equation for the reaction can be written as
AgNO₃(aq) + NaCl (aq) → AgCl(s) + NaNO₃(aq)
To determine the enthalpy change, the following equation applies
To calculate the heat (Q):
Next, we need to calculate the number of moles involved in the reaction (n):
With these two values, we can substitute them into the first equation:
