true
false
question 10
stimulants prevent the reuptake of each of the following neurotransmitters except.
dopamine
endorphins
serotonin
norepinephrine

Explanation:

Question 9

Opioids are chemically similar to endorphins (the body's natural opioids), not serotonin. Serotonin has a different chemical structure and function related to mood, etc. So the statement is false.

Stimulants (like amphetamines, cocaine) typically prevent reuptake of dopamine, serotonin, and norepinephrine to increase their levels in synapses. Endorphins are natural opioids and stimulants do not target endorphin reuptake.

Answer:

False
