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) presynaptic excitation at an excitatory synapse
C) presynaptic inhibition at an excitatory synapse
D) opening of chloride channels on a postsynaptic cell with no active transport of chloride ions
E) opening of potassium channels on the postsynaptic cell

Question

Quizplus · Accepted Answer

Presynaptic excitation at an excitatory synapse increases the release of neurotransmitters that can bind to receptors on the postsynaptic cell, thereby increasing the likelihood of an action potential being generated in the postsynaptic cell.
