In the central nervous system, the neurotransmitter, serotonin, controls the emotions and eating and sleeping patterns of an individual.  Ecstasy is a drug. Its shape is similar to serotonin, and it is more readily taken into the axon terminal from the synapse by the serotonin transporter. When ecstasy interacts with the transporters, it also causes the transporters to release more serotonin into the synapse. Ecstasy also affects the reward pathway in the brain by increasing the release of dopamine.      Which of the following statements does NOT describe the effects of ecstasy on synaptic transmission in our central nervous system? a. Ecstasy blocks the postsynaptic receptor for serotonin. b. Ecstasy increases the duration of serotonin presence in the synapse. c. Ecstasy encourages the axon terminal to release more serotonin neurotransmitters. d. Ecstasy use results in a severe shortage of serotonin when the effects of the ecstasy wear off.
