Th e enzyme-catalyzed conversion of a substrate at 25°C has a Michaelis constant of 0.045 mol dm−3. Th e rate of the reaction is
Elis [28]

Answer:

1.620\times 10^{-3} mol/dm^3 sis the maximum velocity of this reaction.

Explanation:

Michaelis–Menten 's equation:

v=V_{max}\times \frac{[S]}{K_m+[S]}=k_{cat}[E_o]\times \frac{[S]}{K_m+[S]}

V_{max}=k_{cat}[E_o]

v = rate of formation of products =

[S] = Concatenation of substrate

[K_m] = Michaelis constant

V_{max} = Maximum rate achieved

k_{cat} = Catalytic rate of the system

[E_o] = Initial concentration of enzyme

We have :

K_m=0.045 mol/dm^3

v=1.15 mmol/dm^3 s=1.15\times 10^{-3} mol/dm^3 s

[S]=0.110 mol/dm^3

v=V_{max}\times \frac{[S]}{K_m+[S]}

1.15\times 10^{-3} mol/dm^3 s=V_{max}\times \frac{0.110 mol/dm^3}{[(0.045 mol/dm^3)+(0.110 mol/dm^3)]}

V_{max}=\frac{1.15\times 10^{-3} mol/dm^3 s\times [(0.045 mol/dm^3)+(0.110 mol/dm^3)]}{0.110 mol/dm^3}=1.620\times 10^{-3} mol/dm^3 s

1.620\times 10^{-3} mol/dm^3 sis the maximum velocity of this reaction.
