Question
The substance binding to one receptor subtype as an agonist and to another as an antagonist is called:a.Competitive antagonistb.Partial agonistc.Agonist-antagonistd.Irreversible antagonist
Solution
The substance that binds to one receptor subtype as an agonist and to another as an antagonist is called an Agonist-Antagonist.
Here's a step-by-step explanation:
-
An agonist is a substance that binds to a specific receptor and triggers a response in the cell. This is often a molecule that mimics the action of a naturally occurring substance.
-
An antagonist, on the other hand, is a substance that binds to a receptor but does not trigger a response in the cell. Instead, it blocks the receptor and prevents it from being activated by agonists.
-
Therefore, a substance that can act as both an agonist and an antagonist (depending on the receptor subtype it binds to) is called an agonist-antagonist.
So, the correct answer is c. Agonist-Antagonist.
