Examples of membrane receptors:
- Ligand, located outside the cell
- Ligands are connected to specific receptor proteins based on the shape of the active site of the protein.
- The receptor releases the second messenger after the ligand is connected to the receptor.
<h2>Further Explanation
</h2>
In biochemistry and pharmacology, receptors are protein molecules that receive chemical signals from outside the cell.
Receptors can be bound to cell membranes, cytoplasm, or the nucleus, each of which can only be attached by certain types of signaling molecules. Signaling molecules attached to a receptor are called ligands, which can be a peptide or other small molecules such as neurotransmitters, hormones, drugs, or toxins.
Receptor proteins can be classified by their location. Transmembrane receptors include receptors connected with ion channels (ionotropic), receptors connected to protein G (metabotropic), and receptors connected with enzymes.
Not every ligand that binds to the receptor also activates the receptor. The ligand class can be divided into:
- Agonist (full)
- Partial agonist
- Antagonist
- Inverse agonist
- Allosteric modulator
Receptors capable of producing biological responses in the absence of bound ligands are said to display "constitutive activity".
