Reuptake is the absorption of:
A) neurotransmitters by the postsynaptic neuron.
B) neurotransmitters by the presynaptic neuron.
C) nutrients and waste products by glial cells.
D) neurotransmitters by glial cells.

Question

Quizplus · Accepted Answer

Reuptake is the process by which neurotransmitters are absorbed by the presynaptic neuron to be recycled or degraded. This helps regulate the levels of neurotransmitters in the synapse and prevent overstimulation of the postsynaptic neuron. Choice A is incorrect because the postsynaptic neuron receives, rather than absorbs, neurotransmitters. Choice C and D are also incorrect because they refer to the functions of glial cells, which are not directly involved in reuptake.
