Match each of the following terms from the Michaelis-Menten equation to its correct definition.
1) V max A) numerically equal to the substrate concentration at 0.5 V max
2) k cat B) rate of a reaction when enzyme is saturated with substrate
3) k cat/K M C) enzyme efficiency
4) K M D) number of substrate molecules turned over by enzyme
a. 1:C; 2:D; 3:A; 4:B
b. 1:B; 2:C; 3:D; 4:A
c. 1:D; 2:B; 3:A; 4:C
d. 1:B; 2:D; 3:C; 4:A

Respuesta :

Answer:

d. 1:B; 2:D; 3:C; 4:A

Explanation:

The Michaelis-Menten equation is:

[tex]V_{0}=V_{max}\frac{[substrate]}{[substrate]+K_{m}}[/tex]

Also

[tex]V_{0}=K_{cat}E_{0}\frac{[substrate]}{[substrate]+K_{m}}[/tex]

Where

Kcat = turn over number [ number of substrate molecules turned over by enzyme]

Vmax = Maximum rate (rate of a reaction when enzyme is saturated with substrate)

Km = is the substrate concentration when the V is numerically equal to half of Vmax

Kcat / Km = Enzyme efficiency.
