Answer : The value of
for the receptor-ligand interaction is ![27.9\mu M](https://tex.z-dn.net/?f=27.9%5Cmu%20M)
Explanation :
The equilibrium reaction between receptor and ligand will be:
(forward reaction)
(backward reaction)
where,
R = receptor
L = ligand
[RL] = receptor-ligand complex
As we know that,
![K_f=\frac{1}{K_d}](https://tex.z-dn.net/?f=K_f%3D%5Cfrac%7B1%7D%7BK_d%7D)
The expression of
is:
![K_f=\frac{[RL]}{[R][L]}](https://tex.z-dn.net/?f=K_f%3D%5Cfrac%7B%5BRL%5D%7D%7B%5BR%5D%5BL%5D%7D)
As we are given that:
Total [R] = ![50\mu M](https://tex.z-dn.net/?f=50%5Cmu%20M)
Total [L] = ![100\mu M](https://tex.z-dn.net/?f=100%5Cmu%20M)
Free [R] = ![15\mu M](https://tex.z-dn.net/?f=15%5Cmu%20M)
Bound [R] = ![50-15=35\mu M](https://tex.z-dn.net/?f=50-15%3D35%5Cmu%20M)
Bound [L] = Bound [R] = ![35\mu M](https://tex.z-dn.net/?f=35%5Cmu%20M)
Free [L] = ![100-35=65\mu M](https://tex.z-dn.net/?f=100-35%3D65%5Cmu%20M)
Now put all the given values in above expression, we get:
![K_f=\frac{[RL]}{[R][L]}](https://tex.z-dn.net/?f=K_f%3D%5Cfrac%7B%5BRL%5D%7D%7B%5BR%5D%5BL%5D%7D)
![K_f=\frac{(35)}{(15)(65)}](https://tex.z-dn.net/?f=K_f%3D%5Cfrac%7B%2835%29%7D%7B%2815%29%2865%29%7D)
![K_f=0.0358\mu M^{-1}](https://tex.z-dn.net/?f=K_f%3D0.0358%5Cmu%20M%5E%7B-1%7D)
Now we have to calculate the value of
for the receptor-ligand interaction.
![K_f=\frac{1}{K_d}](https://tex.z-dn.net/?f=K_f%3D%5Cfrac%7B1%7D%7BK_d%7D)
![0.0358\mu M^{-1}=\frac{1}{K_d}](https://tex.z-dn.net/?f=0.0358%5Cmu%20M%5E%7B-1%7D%3D%5Cfrac%7B1%7D%7BK_d%7D)
![K_d=27.9\mu M](https://tex.z-dn.net/?f=K_d%3D27.9%5Cmu%20M)
Therefore, the value of
for the receptor-ligand interaction is ![27.9\mu M](https://tex.z-dn.net/?f=27.9%5Cmu%20M)
-4x - 10 = 12
-4x - 10 (+10) = 12 (+10)
-4x = 22
-4x/-4 = 22/-4
x = 5.5
hope this helps
