Calculate the degree of inhibition of an inhibitor on the free enzyme if the [I] = 3 μM and the KI = 6 μM.
A
α = 1.5
B
α = 2
C
α = 4
D
α = 3.5
E
α = 0.5
Verified step by step guidance1
Understand that the degree of inhibition (α) is calculated using the formula: α = 1 + ([I] / KI).
Identify the given values: the concentration of the inhibitor [I] is 3 μM, and the inhibition constant KI is 6 μM.
Substitute the given values into the formula: α = 1 + (3 μM / 6 μM).
Simplify the expression inside the parentheses: 3 μM / 6 μM = 0.5.
Add 1 to the result from the previous step to find α: α = 1 + 0.5.
