After release,neurotransmitters are deactivated in the synapse by
A) reuptake.
B) enzymatic degradation.
C) G proteins.
D) all of the above
E) both A or B

Question

Quizplus · Accepted Answer

Neurotransmitters are typically deactivated in the synapse by either being taken back up into the presynaptic neuron (reuptake) or being broken down by enzymes. Both of these processes are examples of deactivation by removal, as the neurotransmitter is either removed from the synapse or rendered ineffective through degradation. While G proteins can play a role in the regulation of neurotransmitter release, they are not directly involved in the deactivation of neurotransmitters in the synapse. Therefore, the best choice is E - both A or B.
