Increased calcium ion permeability of the presynaptic terminal cell membrane is caused by an ______________.Multiple Choiceacetylcholinesodium ionsaction potentialincreased concentration of calcium ions

An action potential arriving at the presynaptic terminal causesMultiple Choicevoltage-gated sodium ion channels to open, and sodium ions to diffuse out of the cell.voltage-gated calcium ion channels to open, and calcium ions to diffuse into the cell.voltage-gated sodium ion channels to open, and sodium ions to diffuse into the cell.ligand-gated sodium channels to open, and sodium ions to diffuse out of the cell.acetylcholine to diffuse into the cell.

Action potentials arriving at a presynaptic terminal causeMultiple Choicerelease of neurotransmitter.calcium ion channels to close.calcium ion channels to open.breakdown of acetylcholine.

The neurotransmitter at the neuromuscular junction increases permeability of the muscle cell membrane to ____________.Multiple Choicecalcium ionsphosphatesodium ionscholine

As a result of calcium ions diffusing into the presynaptic cell,Multiple Choiceacetylcholine is actively transported to the postsynaptic neuron.synaptic vessels migrate to the plasma membrane and release acetylcholine.sodium ions diffuse into the cell.acetylcholine is actively transported from the presynaptic neuron.ligand-gated sodium channels open.
