Expert Solution
Step 1
Neurotransmission is controlled by several different factors: the readiness and rate-of-synthesis of the neurotransmitter, the release of that neurotransmitter, the starting point activity of the postsynaptic cell, the number of presented postsynaptic receptors for the neurotransmitter to fix to, and the subsequent removal or deactivation of the neurotransmitter by enzymes or presynaptic reuptake.
