Question

Quizplus · Accepted Answer

Steroid hormones, such as cortisol and testosterone, are synthesized from cholesterol.

Answer: E
 Vasopressin, also known as antidiuretic hormone (ADH), is synthesized in the hypothalamus and transported to the posterior pituitary for release into the bloodstream.

The other options are false: 
B) Thyroid hormones are not catecholamines, they are derived from the amino acid tyrosine.
C) The hormones of the adrenal cortex, such as cortisol and aldosterone, have a different structure from the neurotransmitters of adrenergic neurons, such as epinephrine and norepinephrine.
D) Peptide hormones, such as insulin and growth hormone, do not require binding proteins for transport in the blood. However, some steroid hormones, such as cortisol, do require binding proteins for transport.
