Lecture 6: Neurotransmitter Systems Flashcards
1
Q
What are the two types of neurotransmitter, distinguished by their synthesis?
A
Small molecule neurotransmitters and peptide neurotransmitters.
2
Q
What is it called when two different neurotransmitters are released from the same vesicle?
A
Co-release.
3
Q
What is it called when two different neurotransmitters are released from the same synaptic terminal but from separate vesicles?
A
Co-transmission.
4
Q
Which cell does the glutamate-glutamine cycle involve?
A
Glial cell. Glial cells take up extracellular glutamate, turn it into glutamine (using glutamine synthetase), and glutamine then goes back into the presynaptic terminal.
5
Q
All dopamine receptors are ligand gated ion channels or GPCRs?
A
They are all GPCRs.
