Question

If a drug is designed to block the action of a particular enzyme, what would happen if the drug-enzyme interaction had a very high dissociation constant? A1. Binding to the enzyme would require larger dosages of the drug. A2. The drug would bind so tightly it would never dissociate, effectively blocking the enzyme. A3. The drug would be degraded quickly by the enzyme. A4. The drug would enhance the action of the enzyme rather than blocking it. A5. The dissociation constant is not relevant, what matters is the particular drug structure.

Explanation / Answer

Correct option is A1 larger dosages of drug would require as it has higher dissociation constant it will dissociate faster and less than 50% of drug would be available for enzyme receptor binding by which high amounts of drug would be required higher the dissociation constant low Will be drug binding affinity to receptor.
