After neurotransmitter molecules are released, they may be broken down by enzymes, or they may be re-absorbed back into the axon, a process known as
A) inhibition.
B) neurogenesis.
C) refraction.
D) reuptake.
Answer: D
Rationale: Reuptake is a process where neurotransmitter molecules that have been released into the synapse are re-absorbed into the axon terminals of the presynaptic neuron. Reuptake is a very important process. It is a sort of natural recycling system for neurotransmitters.
