Large protein molecules
What happens when a molecule or drug binds to a biochemical receptor?
The receptor changes shape
Which type of drug interacts with the receptor site and produces no response but prevents the action of the body’s natural active compound?
Antagonist drug
What is the primary effect of an antagonist drug on the receptor site?
Blocks the receptor site
Which of the following best describes the action of an antagonist drug?
It prevents the action of the natural active compound
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.
