The members of a legislature are called legislators. In a democracy, legislators are most commonly popularly elected, although indirect election and appointment by the executive are also used, particularly for bicameral legislatures featuring an upper chamber
Catecholamines are released into the blood when a person is under physical or emotional stress. The main catecholamines are dopamine, norepinephrine, and epinephrine (which used to be called adrenalin). This test is used to diagnose or rule out certain rare tumors, such as pheochromocytoma or neuroblastoma.
In other words, high insulin levels inhibit the use of body fat for energy in the body. The researchers found in their studies that high levels of insulin can block stress hormones known as catecholamines, which normally cause the release of cellular energy. Adrenaline is the best known example of a catecholamine. For normal metabolism to occur, the body needs a balanced input of insulin and catecholamines. One of the actions of insulin --, the main energy storage hormone, is to block activation of the protein kinase A (PKA) enzyme.
