Reuptake of neurotransmitters is the process by which neurotransmitters ________
A) are repeatedly released into the synapse.
B) are reabsorbed by the axon.
C) stimulate the post-synaptic neuron to fire.
D) are connected to hormones.

Question

Quizplus · Accepted Answer

Reuptake is the process by which neurotransmitters are reabsorbed by the axon terminals of the pre-synaptic neuron, after they have been released into the synapse to transmit signals to the post-synaptic neuron. This is important for regulating neurotransmitter levels and preventing continuous stimulation of the post-synaptic neuron.  Option A is incorrect because neurotransmitters are not repeatedly released unless there is continuous stimulation of the pre-synaptic neuron. Option C is incorrect because neurotransmitters do not directly stimulate the post-synaptic neuron to fire, they only transmit signals. Option D is incorrect because neurotransmitters are not connected to hormones.
