When cocaine interferes with reuptake receptors on a presynaptic neuron, all of the following occur except

a) the postsynaptic cell is overstimulated
b) excess neurotransmitters remain in the synaptic cleft
c) the amount of neurotransmitter released by the presynaptic neuron is increased
d) the number of neurotransmitter receptors decreases

The correct answer is letter D, the number of neurotransmitter receptors decreases. 

Cocaine is a stimulant drug. Stimulants are drugs that induce a feeling of euphoria and elation to a person who is taking them. Stimulant drugs also have the capacity to transmit neurosynaptic at an increased rate. Coffee is an example of caffeine that actually contains small traces of cocaine-like chemicals, this is the reason why you feel awake once you have it in your system.
