A pharmacology student asks the instructor what an accurate description of a drug agonist is. What is the instructor's best response?
- A. A drug that reacts with a receptor site on a cell preventing a reaction with another chemical on a different receptor site

Correct Answer: C
Rationale: Agonists are drugs that produce effects similar to those produced by naturally occurring neurotransmitters, hormones, or other substances found in the body. Noncompetitive antagonists are drugs that react with some receptor sites preventing the reaction of another chemical with a different receptor site. Drug-enzyme interactions interfere with the enzyme systems that stimulate various chemical reactions.
