Question

cocaine has two effects on synaptic transmission: it impairs reuptake of dopamine and it causes more dopamine to be released into the synaptic cleft. would cocaine be classified as an agonist or antagonist? why?

Explanation:

Agonists enhance neurotransmitter effects. Cocaine increases dopamine in the synaptic cleft by blocking reuptake and promoting release, mimicking dopamine's action. So it acts as an agonist.

Answer:

Cocaine would be classified as an agonist.
