Question

Which would cause postsynaptic stimulation to end?

A. Increased release of neurotransmitters.
B. Binding of neurotransmitters to receptors.
C. Reuptake of neurotransmitters.
D. Action potential reaching the axon terminal.

Answer 1

Postsynaptic stimulation ends when neurotransmitters are reabsorbed by the neuron that released them, a process known as reuptake.

Step-by-step explanation:

Postsynaptic stimulation ends due to the reuptake of neurotransmitters. This is a process during which neurotransmitters are pumped back into the neuron that released them, clearing the synaptic cleft. This allows for a clear "on" and "off" state between signals and regulates the production of neurotransmitters. Therefore, the correct answer is C. Reuptake of neurotransmitters. It is not the increased release of neurotransmitters, binding of neurotransmitters to receptors, or the action potential reaching the axon terminal that causes the end of postsynaptic stimulation.
