Which statement is true about steroid hormones?
A) Insulin is a steroid hormone.

D) The hormone-receptor complex can enter the nucleus.
E) Steroid hormones have different complexes of 4-carbon rings.

Question

Quizplus · Accepted Answer

Steroid hormones can pass through the cell membrane because they are lipid-soluble, and bind to receptors inside the cell, including in the nucleus. Once bound, the hormone-receptor complex can modify gene expression, thereby producing a slower but more sustained response compared to peptide hormones, which typically bind to cell surface receptors and produce more rapid but shorter-lived responses. Insulin is not a steroid hormone, and while steroid hormones can have different functional groups attached to their carbon rings, all share the basic structure of four fused rings.
