Question

acetylcholine has which effect on the postsynaptic neuron? multiple choice ligand - gated calcium ion channels open, and calcium diffuses in. ligand - gated sodium ion channels open, and sodium diffuses in. terminal vessels migrate to the plasma membrane. voltage - gated calcium ion channels open, and calcium diffuses in. voltage - gated sodium ion channels open and sodium diffuses in

Explanation:

Acetylcholine is a neurotransmitter. When it binds to its receptors on the postsynaptic neuron, ligand - gated sodium ion channels open, allowing sodium ions to diffuse into the neuron, which can depolarize the neuron and potentially initiate an action potential.

Answer:

B. Ligand - gated sodium ion channels open, and sodium diffuses in.
