A)They are derived from peptides or proteins.

E)They produce cAMP molecules in target tissue.

Question

Quizplus · Accepted Answer

Steroid hormones are derived from cholesterol and can enter the cell membrane to interact with intracellular receptors. Once bound, they can influence the activity of DNA and cause changes in gene expression in the target tissue. They do not interact with receptors on the exterior surface of the cell membrane, utilize second messenger systems, or produce cAMP molecules in target tissue.
