In the Second-Messenger

In the second-messenger

A) a small amount of one hormone (the second messenger) is required to release another.
B) a tropic hormone (the first messenger) stimulates secretion of another hormone (the second messenger) .
C) the hormone first binds to a specific surface receptor, whereupon the hormone-receptor complex moves into the cell to combine with a specific intracellular receptor.
D) releasing hormones (the first messenger) from the hypothalamus regulate many anterior pituitary hormones (the second messenger) .
E) a hormone (the first messenger) binds to surface receptors activating adenylate cyclase, catalyzing cAMP formation.
