An antibody binds to an epitope with high affinity. What does this imply about the dissociation constant (Kd) and the induced fit model?

• A. The Kd is high, indicating weak binding due to the induced fit model.
• B. The Kd is high, indicating strong binding due to the induced fit model.
• C. The Kd is low, indicating weak binding due to the induced fit model.
• D. The Kd is low, indicating strong binding due to the induced fit model.

Answer: (D)
