When an action potential reaches the nerve terminal: neurotransmitter molecules

Question

When an action potential reaches the nerve terminal: neurotransmitter molecules are released from the nerve terminal, bind to and open the potassium channels on the cell body of the next neuron, and may initiate an action potential in that neuron sodium ions are released from the nerve terminal, enter the cell body of the next neuron through its sodium channels and may initiate an action potential in that neuron calcium ions are released from the nerve terminal, bind to and open the sodium channels on the cell body of the next neuron, and may initiate an action potential in that neuron potassium ions are released from the nerve terminal, enter the cell body of the next neuron through its potassium channels and may initiate an action potential in that neuron neurotransmitter molecules are released from the nerve terminal, bind to and open the sodium channels on the cell body of the next neuron, and may initiate an action potential in that neuron When an action potential reaches the nerve terminal: neurotransmitter molecules are released from the nerve terminal, bind to and open the potassium channels on the cell body of the next neuron, and may initiate an action potential in that neuron sodium ions are released from the nerve terminal, enter the cell body of the next neuron through its sodium channels and may initiate an action potential in that neuron calcium ions are released from the nerve terminal, bind to and open the sodium channels on the cell body of the next neuron, and may initiate an action potential in that neuron potassium ions are released from the nerve terminal, enter the cell body of the next neuron through its potassium channels and may initiate an action potential in that neuron neurotransmitter molecules are released from the nerve terminal, bind to and open the sodium channels on the cell body of the next neuron, and may initiate an action potential in that neuron

Explanation / Answer

Answer: Option E is correct.

Explanation: When the action potential reaches a nerve terminal, a neurotransmitter is released into the synaptic cleft with the help of Ca+2 ions. The released neurotransmitter causes opening of Na+ channels in the post-synaptic neuron and may initiate the action potential in that neuron.
