Which ion triggers the fusion of intracellular synaptic vesicles with the inside of the membrane in the terminal axon?

What is the role of Acetylcholinesterase in the muscle cell membrane?
What is the role of Acetylcholinesterase in the muscle cell membrane?
- It makes new Acetylcholine neurotransmitters by binding with acetic acid molecules.
- It triggers the voltage-gated calcium channels to change shape and allow calcium ions to flow inside the cell.
- It binds with ligand-gated Na+ channels on the postsynaptic membrane and opens Na+ channels.
- It binds with acetic acid and breaks down Acetylcholine into choline and acetic acid. (correct)
What happens when Acetylcholine binds with ligand-gated Na+ channels on the postsynaptic membrane?
What happens when Acetylcholine binds with ligand-gated Na+ channels on the postsynaptic membrane?
- It breaks down Acetylcholine into choline and acetic acid.
- It opens Na+ channels and allows Na+ ions to pass through and go inside the cell. (correct)
- It makes new Acetylcholine neurotransmitters by binding with acetic acid molecules.
- It triggers the voltage-gated calcium channels to change shape and allow calcium ions to flow inside the cell.
