Neurotransmitters originating in neuron A excite neuron B by __________.
A) depolarizing neuron A
B) repolarizing neuron A
C) repolarizing neuron B
D) depolarizing neuron B

Question

Quizplus · Accepted Answer

Neurotransmitters are chemical messengers that transmit signals between neurons. When neurotransmitters are released from neuron A and bind to receptors on neuron B, they cause a change in the membrane potential of neuron B, which can either increase (depolarize) or decrease (hyperpolarize) the likelihood that neuron B will fire an action potential. In this case, the question asks which option would cause neuron B to be excited, and the only option that fits is depolarizing neuron B (Choice D).
