Question

If the association rate constant (ka) is 2 x 10^7 M^-1s^-1 and the dissociation rate constant (kd) is 2 x 10^-4 s^-1, what is the ratio ka/kd and what does it indicate?

Accepted Answer

1 x 10^3, indicating a moderate affinity between the protein and ligand.

Answer

1 x 10^-3, indicating a weak affinity between the protein and ligand.

Answer

1 x 10^-11, indicating a weak affinity between the protein and ligand.

Answer

1 x 10^11, indicating a strong affinity between the protein and ligand.
