#. Serotonin 5-HT2 receptors are metabotropic receptor believed to be involved in the action of
hallucinogens; they might also play a role in depression and psychosis. The dose-response curves
below represent drugs A, B, and C that possess affinity for 5-HT2 receptors, but differ in their
intrinsic activity.
Effect vs. Log D Conc graph
Drug C (100% Effect with higher curve)
Drug A ( Lower curve)
