What would be the effect on serotonin levels if you inhibit SERT?
What would be the effect on serotonin levels if you inhibit SERT?
- Serotonin would not be produced by the neuron
- Serotonin levels would remain the same in the extracellular state
- Serotonin levels would decrease in the extracellular state
- Serotonin levels would increase in the extracellular state (correct)
What is the role of acetylcholinesterase (AChE) in neuronal signaling?
What is the role of acetylcholinesterase (AChE) in neuronal signaling?
- AChE breaks down acetylcholine after release from synaptic vesicles (correct)
- AChE converts glutamate into GABA for synaptic transmission
- AChE transports acetylcholine back into the neuron for recycling
- AChE inhibits the release of acetylcholine from neurons
What is the fate of choline after it is transported back into the neuron by choline transporter (CHT)?
What is the fate of choline after it is transported back into the neuron by choline transporter (CHT)?
- It reacts with Acetyl CoA to form GABA
- It is converted back to acetylcholine (correct)
- It is excreted as waste from the neuron
- It triggers the release of serotonin from the neuron
