Which of the following neurotransmitter is a catecholamine?
Dopamine, norepinephrine, and epinephrine are catecholamines.
Where is tyrosine found?
Tyrosine is an amino acid that is found all over the body in its polypeptide chains and proteins. It also serves as the precursor for the catecholamine neurotransmitter dopamine in the nervous system.
Is epinephrine a steroid a catecholamine a peptide or a iodinated amino acid derivative?
catecholamine
Is Atropine a catecholamine?
yes it is
Is serotonin a catecholamine?
no serotonin is not a catecholamine. Catecholamines are dopamine, epinepherine and norepinepherine.

Is NE a complex molecule?
No, NE (norepinephrine) is not considered a complex molecule. It is a relatively simple structure, classified as a catecholamine, with a straightforward arrangement of atoms including a benzene ring, two hydroxyl groups, and an amine group. While it plays a crucial role in the body as a neurotransmitter and hormone, its molecular structure itself is not complex when compared to larger biomolecules like proteins or nucleic acids.
Why is epinephrine considered both a hormone and a neurotransmitter?
Epinephrine is considered both a hormone and a neurotransmitter because it is released into the bloodstream by the adrenal glands to regulate various bodily functions as a hormone, and it is also released by nerve cells in the brain and nervous system to transmit signals between neurons as a neurotransmitter.
When is epinephrine considered to be a neurotransmitter and when is it considered to be a hormone?
it's a hormone when it is produced by the adrenal gland and a nuerotransmitter when it is secreted by a nueron.
What mediator is considered to be both a neurotransmitter and a hormone?
Norepinephrine is a mediator that acts as both a neurotransmitter in the central and peripheral nervous system and as a hormone in the bloodstream. It plays a role in various functions including regulating heart rate, blood pressure, and the body's fight or flight response.
Which inhibitory neurotransmitter is considered to be the most prevalent in the mammalian CNS?
GABA, or gamma amino butyric acid, is made from glutamate in the cells of the brain. This inhibitory neurotransmitter blocks nerve impulses.
What is the function of norepinophine?
Norepinephrine is a catecholamine with multiple roles including as a hormone and a neurotransmitter.Areas of the body that produce or are affected by norepinephrine are described as noradrenergic. One of the most important functions of norepinephrine is its role as the neurotransmitter released from the sympathetic neurons affecting the heart. An increase in norepinephrine from the sympathetic nervous system increases the rate of contractions
