The neurotransmitter is Dopamine.
The following combinations of neurotransmitters seem to be at play in
those who suffer from ADHD is Serotonin, dopamine, and norepinephrine. Neurotransmitters,
also known as chemical messengers, are endogenous chemicals that enable
neurotransmission. They transmit signals across a chemical synapse, such as a
neuromuscular junction.
Cell regulation is conducted by special proteins. These special
proteins are enzymes which help in the regulation of bodily function. They hasten
the chemical reaction such as pepsin. Pepsin is a protein that helps in the
digestion of food in the body.
