Q. How do steroid hormones differ from amino acid-based hormones?
A. steroid hormones are water soluble whereas amino acid based hormones are not.
B. the receptors for steroid hormones are only in the cytoplasm or the nucleus (and amino acid-based hormones are not)
C. steroid hormones are made only in the adrenal glands, while amino acidbased hormones are produced by a variety of glands.
D. steroid hormones activate a G-protein and exert their effect via “second messengers”, but the action of amino acid-based hormones results directly on binding to their receptor.
Answer: the receptors for steroid hormones are only in the cytoplasm or the nucleus (and amino acid-based hormones are not)
