The Action of Agonists (A), Partial Agonists (B), Antagonists (C), and Inverse Agonists (D) Can Be Interpreted As Changing the Balance Between the Active and Inactive Forms of the Receptor In This Case, in the Absence of Agonist, the Receptor is in the Activated State 20% of the Time. This Percentage Changes Based on the Nature of the Ligand Bound to the Receptor.
