Question

Your body has designed a "traffic signal" for action potentials traveling from one neuron to another. In this system, a red light represents _________.

(A) An excitatory neurotransmitter
(B) An inhibitory neurotransmitter
(C) A combination of excitatory and inhibitory neurotransmitters
(D) None of these options; once started, an action potential never stops

Answer 1

The correct answer is B. An inhibitory neurotransmitter

Step-by-step explanation:

In biology, a neurotransmitter refers to a chemical or substance that act as messengers by transmitting information in the nervous system. Additionally, a neurotransmitter is inhibitory if it stops or reduces the process of information transmission, which means inhibitory neurotransmitters stop action potentials or information going from one neuron to another and therefore this type of neurotransmitter represent red lights in the nervous system as they stop signals or information.
