The correct answer is A, as the statement is true. The enzyme catchol-o-methyl transferase (COMT) in the nervous system is important in the degradation of catecholamines by neuroglia cells.
Explanation:
Catechol-O-methyltransferase, abbreviated as COMT, is one of several enzymes in the body involved in the degradation of catecholamines such as dopamine, norepinephrine and adrenaline. The enzyme works by transferring a methyl group to the signal substance from the SAM donor group (S-adenosylmethionine).
