Question

Catecholamines
A) include cortisol, aldosterone, and testosterone.
B) are secreted by the adrenal cortex.
C) lower plasma glucose levels.
D) include epinephrine (adrenalin) and norepinephrine.

Accepted Answer

Catecholamines include epinephrine (adrenalin) and norepinephrine, which are secreted by the adrenal medulla and increase plasma glucose levels. Option A is incorrect as cortisol, aldosterone, and testosterone are steroid hormones. Option B is incorrect as catecholamines are secreted by the adrenal medulla, not cortex. Option C is also incorrect as catecholamines increase plasma glucose levels.
