A group of investigators studies the mechanism of catecholamine synthesis regulation.In animal experiments hypophysectomy induced a decrease in epinephrine secretion by the adrenals.Decrease activity of which of the following enzymes is most likely responsible for the effect observed?
a-Phenylalanine hydroxylase
b-Tyrosine hydroxylase
c-Dopa decarboxylase
d-Dopamine beta hydroxylase
e-Phenylethanolamine n-methyltransferase
f-Catechol-methyltransferase
g-Monoamine oxydase

well, let the investigator worry about the q. too hard for us...
ok, just kidding
really, not much idea. why it has something to do with hypophysectomy?? twist coming??
I only know in adrenal, you coulud use e-Phenylethanolamine n-methyltransferase to convert NE to epinepherine.
but in this case, do not know.
Maybe still EEEEE
