Answer:
The given blanks can be filled with vesicle, release, and blocking the action of enzymes.
Explanation:
The psychoactive are the drugs, which instigates the discharge of excitatory neurotransmitter as glutamate, and the antipsychotics diminish the excitation of the neuron. The mentioned drugs could enhance the effect of a neurotransmitter by inducing the leak of neurotransmitter due to the dissociation of a synaptic vesicle, by preventing the release of the neurotransmitter from the presynaptic membrane, and by obstructing the activity of the enzymes that usually breaks down the neurotransmitter.
