Which of the following would increase the likelihood of an action potential being generated in a postsynaptic cell?
A)opening of chloride channels on a postsynaptic cell that actively transports chloride ions out of the cell
B)opening of chloride channels on a postsynaptic cell with no active transport of chloride ions
C)opening of potassium channels on the postsynaptic cell
D)presynaptic excitation at an excitatory synapse
E)presynaptic inhibition at an excitatory synapse

Question

Quizplus · Accepted Answer

Presynaptic excitation at an excitatory synapse increases the likelihood of an action potential by depolarizing the postsynaptic membrane, bringing it closer to the threshold for firing an action potential.
