Question

Quizplus · Accepted Answer

Monoamines are neurotransmitters that are made up of a single amine group. They are divided into two groups based on their chemical structure: catecholamines and indolamines. Catecholamines include dopamine, epinephrine, and norepinephrine, while indolamines include serotonin and tryptamine. Therefore, option C, "catecholamines and indolamines," is the correct answer. Options A, B, D, and E are not correct as they do not accurately describe the two groups of monoamines.
