The release of this catecholamine cannot be controlled in pheochromocytoma, and both it and an unmethylated precursor are transported by VMAT1.
The release of this catecholamine cannot be controlled in pheochromocytoma, and both it and an unmethylated precursor are transported by VMAT1. While it triggers vasoconstriction in smooth muscle, it dilates blood vessels in skeletal muscle. In the liver, its interaction with its beta-receptors causes glycogen to be broken down into glucose for energy. Frequently used to treat anaphylactic shock and secreted by glands that sit above the kidneys, for 10 points, identify this hormone and neurotransmitter responsible for the "fight or flight" response.
