Wrong - The answer is Neurotransmitter
Those doing their UoP homework in this way are brilliant, yet susceptible to wrong answers.
Neurotransmitters are the chemical messengers released from neurons to activate an adjacent cell, such as another neuron, muscle cell, or gland cell. They allow for communication between nerve cells and other types of cells in the body.
There are three kinds of chemical messengers in the nervous system: Neurotransmitters, endorphins and hormones. 1) Neurotransmitters are released by transmitting neurons. They alter the activity of the receiving neurons. Note that neurotransmitters exist outside of the nervous system as well. Some neurotransmitters are: Serotonin, dopamine, acetylcholine, gamma-aminobutyric acid (GABA), norepinephrine (also a hormone) and glutamate. 2) Endorphins help in pain reduction, pleasure and even memory. 2) Hormones are affects the functioning of organs and are released by glands. Some hormones include: Melatonin, oxytocin, adrenal hormones (cortisol, epinephrine, norepinephrine) and sex hormones (androgens, estrogens and progesterone).
Chemical signals sent between individuals are known as pheromones. These are chemical substances that are produced and released into the environment by one individual to affect the behavior or physiology of another individual of the same species. Pheromones play a role in various social interactions, such as mating, alarm responses, and territory marking.
Chemical potential energy is the energy stored in the chemical bonds of a substance that can be released during a chemical reaction.
It is true that when bonds are broken there is chemical reaction. Then heat energy is released.

The hormone secretin functions as a chemical messenger in the digestive system. It is released by the duodenum in response to the presence of acidic chyme, and it stimulates various organs like the pancreas to release bicarbonate to neutralize the acidity in the small intestine.

A neurotransmitter whose function depends on a second messenger is known as a neuromodulator. Neuromodulators can influence the behavior of neurons by affecting processes like signal transduction or synaptic transmission.
The movie "Kill the Messenger" is a French documentary film that was released in 2006. This film exposes the criminality that was uncovered at the FBI.

The nitrogen in the atmosphere originates from the Earth's crust and mantle, released through volcanic activity and chemical weathering processes.
