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

The correct answer is B. An inhibitory neurotransmitter

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.

photosynthesis makes the glucose that is used in cellular respiration to make atp. the glucose is then turned back into carbon dioxide, which is used in photosynthesis. while water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
