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.

Question

Quizplus · Accepted Answer

The process described in the question is reuptake, in which neurotransmitter molecules that have been released are taken back into the axon terminal for later use. This is different from inhibition (which refers to the blocking of a neurotransmitter's effects), neurogenesis (which refers to the growth of new neurons), or refraction (which refers to the bending of light as it passes through a medium).
