Answer to Question 2

A
Feedback:
When endogenous opioids are released, they are thought to bind to sites on the nerve cell's membrane that block the transmission of pain-conducting neurotransmitters such as substance P and prostaglandins. Endogenous opioids do not occupy cell receptors for neurotransmitters like acetylcholine and serotonin, but efforts are being made to develop pain-modulating drugs that will do so and will also block glutamate receptors and peptides.
