The process illustrated in the figure is related to the neurotransmitter dopamine. Reserpine and most traditional medications used to treat schizophrenia act as antagonists by blocking dopamine receptors or decreasing dopamine levels, as shown in the downward arrow in the figure. The drugs listed in options A and C are either dopamine agonists or reuptake inhibitors and would have the opposite effect of the antagonists. Option D, apomorphine, is a dopamine agonist and would not act as an antagonist.
