Final answer:
Reuptake is a process where neurotransmitters are removed from the synapse and transported back to the end bulbs. This process clears the synapse and regulates neurotransmitter production.
Step-by-step explanation:
Reuptake is a process where neurotransmitters are removed from the synapse and transported back to the end bulbs. This process helps to clear the synapse and regulate the production of neurotransmitter. Once the neurotransmitter is released into the synaptic cleft, it can be reabsorbed by the presynaptic neuron through reuptake.
