Feedback:
Norepinephrine is made by the nerve cells using tyrosine, obtained in the diet. Dihydroxyphenylalanine (dopa) is produced by a nerve, using tyrosine from the diet and other chemicals. With the help of the enzyme dopa decarboxylase, the dopa is converted to dopamine, which in turn is converted to norepinephrine in the axon terminals of adrenergic cells. The norepinephrine then is stored in granules or storage vesicles within the cell.
