Again, using the lock and key analogy, an antagonist is like a key that fits nicely into the lock but doesn’t have the right shape to turn the lock. When this key (antagonist) is inserted in the lock, the proper key (agonist) can’t go into the same lock. WitrynaFrom its name, someone literate in biochemical jargon can figure out it takes monoamine molecules (like serotonin), and degrades them through a process called oxidation.
