Full Question:
Morphine and heroin duplicate the action of ____________.
A) Endorphins
B) Alcohol
C) Cigarettes
D) LSD
Answer:
The correct answer A) is Morphine and heroine duplicate the action of endorphins.
Explanation:
β-Endorphin is a naturally occurring opioid neuropeptide and peptide hormone that is produced in certain neurons within the central nervous system and peripheral nervous system.
Neuropeptides are small protein-like molecules used by neurons to communicate with each other. They are neuronal signalling molecules that influence the activity of the brain and the body in specific ways.
A peptide is a short chain of amino acids.
β-Endorphin is one of three endorphins that are produced in humans, the others of which include α-endorphin and γ-endorphin.
Research shows that it serves as a primary endogenous ligand for the μ-opioid receptor, the same receptor to which the chemicals extracted from opium, such as morphine, derive their analgesic properties.
