The specificity of hormone action derives from
A)target cell receptors that are unique for each hormone.
B)target cell receptors that are unique for all steroid hormones.
C)target cell receptors that are unique for all nonsteroid hormones.
D)target cell receptors that bind only certain neurotransmitters.

Question

Quizplus · Accepted Answer

The specificity of hormone action is determined by the target cell receptors that are unique for each hormone. Each hormone molecule can bind only to specific receptor molecules on target cells, leading to a specific biological response. This specificity allows hormones to coordinate and regulate complex physiological processes in a highly precise manner. Steroid hormones and nonsteroid hormones may have different types of receptors, but the specificity of the interaction between a hormone and its receptor is determined by the chemical structure of the hormone and the shape and chemical properties of the receptor. Neurotransmitters are a different class of signaling molecules that act on receptors in the nervous system, but they are not involved in hormone signaling.
