Receptor Site

Answer 15

specific location on certain cells for certain drugs and normal body substances

Question 16

Agonists

Answer 16

Drugs that bind to specific receptors and produce a drug action

Question 17

Antagonists

Answer 17

Drugs that bind to specific receptors and block agonist drug action or cellular functions are called antagonists
