Cells that secrete epinephrine must contain which enzymes?

Question

Quizplus · Accepted Answer

The synthesis of epinephrine involves several steps, starting with the amino acid tyrosine. Tyrosine is first hydroxylated by tyrosine hydroxylase to form DOPA, which is then decarboxylated by dopa decarboxylase to form dopamine. Dopamine is then hydroxylated by dopamine β-hydroxylase to form norepinephrine. Finally, norepinephrine is methylated by phenylethanolamine N-methyltransferase (PNMT) to form epinephrine. Therefore, all four enzymes are necessary for the synthesis of epinephrine.
