A researcher synthesizes a new molecule called inhibitor X that inhibits the activity of phosphofructokinase (PFK), the enzyme t
Oduvanchick [21]

Answer : The dissociation constant of the PFK‑inhibitor complex is, 5 µM

Explanation :

The expression for reversible competitive inhibition when apparent Km affected by addition of the inhibitor is:

K_m_a=K_m[1+\frac{I}{K_i}]

where,

K_m_a = apparent value = 52 µM

K_m = Michaelis–Menten constant = 40 µM

I = inhibitor concentration = 1.5 µM

K_i = dissociation constant of the PFK‑inhibitor complex

Now put all the given values in the above formula, we get:

52\mu M=40\mu M[1+\frac{1.5\mu M}{K_i}]

K_i=5\mu M

Therefore, the dissociation constant of the PFK‑inhibitor complex is, 5 µM
