Dr.Pohler is a neurobiologist studying ways to enhance the perception of sound in people with hearing difficulties.He discovers a natural neurotransmitter that increases the chance a neuron will fire an action potential,increasing sensitivity to sound.What is the effect of this neurotransmitter on the receiving neuron?
A)Inhibitory,causing hyperpolarization
B)Inhibitory,causing depolarization
C)Excitatory,causing hyperpolarization
D)Excitatory,causing depolarization

Question

Quizplus · Accepted Answer

The neurotransmitter described in the scenario increases the chance that a neuron will fire an action potential, which is an excitatory effect. This suggests that the neurotransmitter causes depolarization, as this is necessary for an action potential to occur. Therefore, the best choice is D) Excitatory, causing depolarization.
