Which statement best describes the action of a steroid hormone on its target cell?
- A.It binds to a receptor on the plasma membrane and directly opens sodium channels.
- B.It diffuses through the plasma membrane and binds to an intracellular receptor, influencing gene expression.Correct answer
- C.It is stored in synaptic vesicles and released into the synaptic cleft.
- D.It acts only by activating adenylate cyclase on the outer surface of the cell.
Solution
Steroid hormones are lipid-soluble and can cross the plasma membrane. They bind intracellular receptors, and the hormone-receptor complex regulates transcription of specific genes.
