NRSC 2125 - Midterm 3, Exam Review Questions and answers, rated A+ What is a drug agonist (full and partial)? - -drug agonist - chemical that binds to & activates a receptor to produce a biological response full agonist - produces the maximum response partial agonist - produces less than the maximum response What is a drug antagonist (competitive/non-competitive)? - -drug antagonist - chemical that binds to & blocks a receptor (does NOT activate), thus blocking or dampening a biologica...

Agonist - Competitive inhibition, binds to active site and causes a signal response in receptive tissue. Antagonist (blocker) - Competitive inhibitor, binds to active site so signal molecules cannot bind but causes no response in receptive tissue, can bind and release eventually.

Example: tetrodotoxin form Fugu fish...
