Question

Describe the catecholamine family of neurotransmitters

A) Catecholamines include dopamine, serotonin, and histamine
B) Catecholamines are exclusively inhibitory neurotransmitters
C) Catecholamines are a subclass of neuropeptides
D) Catecholamines consist of dopamine, norepinephrine, and epinephrine

Answer 1

The catecholamine family of neurotransmitters includes dopamine, norepinephrine, and epinephrine. They are made from the amino acid tyrosine and play important roles in the nervous and endocrine systems.

Step-by-step explanation:

The catecholamine family of neurotransmitters consists of dopamine, norepinephrine, and epinephrine. These neurotransmitters are made from the amino acid tyrosine. Dopamine is part of its own dopaminergic system and is removed from the synapse by transport proteins. Norepinephrine and epinephrine belong to the adrenergic neurotransmitter system and are transported back into the presynaptic cell. The adrenal gland produces these catecholamines to be released into the bloodstream as hormones.
