Question

ecstasy produces a state of high energy and emotional elevation that lasts for hours. this is because it: triggers dopamine release. releases stored serotonin and blocks its reuptake. increases sociability and feelings of connectedness. depletes the brain’s supply of dopamine, serotonin, and norepinephrine.

Explanation:

To determine the correct answer, we analyze the mechanism of Ecstasy (MDMA). Ecstasy is known to primarily affect serotonin: it releases stored serotonin and blocks its reuptake, leading to elevated mood and energy for hours. Triggering dopamine release is more associated with stimulants like amphetamines or rewards, not the main mechanism of Ecstasy for its prolonged emotional elevation. Increasing sociability is an effect, not the cause of the energy/emotional state. Depleting neurotransmitters would lead to negative effects later, not the initial high.

Answer:

B. releases stored serotonin and blocks its reuptake.
