Which term describes a molecule that blocks receptor activation?

Explanation:
An antagonist is a molecule that blocks receptor activation. It binds to the receptor without producing its own activating signal, preventing an agonist from triggering a response. If it binds at the same site as the agonist, it can be overcome by more agonist (competitive antagonism). In contrast, a partial agonist still activates the receptor, just not as fully, and an inverse agonist reduces baseline receptor activity rather than merely blocking activation.
