Answer to Question 1

Answer: D

Answer to Question 2

Answer: The postsynaptic action of many neurotransmitters is terminated via reuptake of the
molecule through the membrane transporter or through enzymatic inactivation. A drug that blocks such a transporter would be expected to raise the synaptic levels of that neurotransmitter, as would a drug that blocks the enzymatic degradation step. For a disease or disorder that is thought to result from a low synaptic activity of that transmitter, blockade of the reuptake or enzymatic process would generate a beneficial effect.
