10 Questions
What type of channels open as the cell depolarizes during neurotransmitter release?
Voltage-sensitive Ca2+ channels
Which protein interacts with Ca2+ to initiate the process of exocytosis during neurotransmitter release?
Synaptotagmin
What ion does the neurotransmitter typically bind to, leading to depolarization of the post-synaptic cell?
Sodium (Na+)
What type of neurotransmitter causes Na+ or Ca2+ to enter the cell?
Glutamate
Which type of receptors are associated with ligand-gated ion channels for producing fast post-synaptic potentials?
Nicotinic receptors
What type of neurotransmitter typically causes hyperpolarization by allowing Cl- to enter the cell?
GABA
Where are small molecule neurotransmitters synthesized?
In the cytosol of the terminal end
How are neuropeptides synthesized?
By precursor proteins in the soma
What is the process of removing neurotransmitters from the synapse called?
Reuptake
Where do vesicles containing neurotransmitters undergo fast anterograde transport to?
Axon terminal end
