Thyroid and steroid hormones, which exert their effect on target cells by way of nuclear receptors, have which of the following characteristics?
A) The selective use of a second messenger
B) The ability to cross the cell membrane of target cells
C) The ability to regulate surface receptor affinity
D) Both lipid solubility and water solubility
Ans: B
Feedback:
Hormones that utilize nuclear receptors enter the target cell (i.e., cross the cell membrane) and bind to receptors in the cell nucleus that are gene regulatory proteins. These hormones do not selectively utilize second messengers, and they do not interact with surface receptors. They are not both lipid and water soluble.
