Study Notes
Biochemical Receptors
- Ligands, hormones, and neurotransmitters are types of molecules that can activate biochemical receptors.
- Biochemical receptors are primarily made of proteins.
Binding of Molecules to Receptors
- When a molecule or drug binds to a biochemical receptor, it triggers a response or signal in the cell.
Antagonist Drugs
- Antagonist drugs interact with the receptor site and produce no response, but prevent the action of the body's natural active compound.
- The primary effect of an antagonist drug on the receptor site is to block the action of an agonist, a molecule that normally binds to the receptor and produces a response.
- An antagonist drug can be described as a molecule that binds to a receptor but does not activate it, thereby blocking the effect of an agonist.
