6 Questions
Which ion triggers the fusion of intracellular synaptic vesicles with the inside of the membrane in the terminal axon?
Calcium (Ca+)
What is the role of Acetylcholinesterase in the muscle cell membrane?
It binds with acetic acid and breaks down Acetylcholine into choline and acetic acid.
What happens when Acetylcholine binds with ligand-gated Na+ channels on the postsynaptic membrane?
It opens Na+ channels and allows Na+ ions to pass through and go inside the cell.
Which ion triggers the voltage-gated Ca+ channels to change shape and allow Ca+ to move into the cytosol of the terminal axon?
None of the above
What is the role of Acetylcholine in the skeletal muscle cell activation process?
It binds with ligand-gated Na+ channels on the postsynaptic membrane.
What happens to the Acetylcholine that is broken down by Acetylcholinesterase in the muscle cell membrane?
It goes back into the terminal axon to make new Acetylcholine neurotransmitters.
