Which of the following statements is true of steroid receptors?
A) The receptor molecules are themselves lipids or glycolipids.
B) The receptor may be inside the nucleus of a target cell.
C) The unbound steroid receptors are quickly recycled by lysosomes.
D) Steroid receptors are typically bound to the external surface of the nuclear membrane.

Question

Quizplus · Accepted Answer

Steroid receptors can be found inside the nucleus of target cells. Once a steroid hormone binds to the receptor, the receptor-hormone complex moves into the nucleus where it binds to DNA and regulates gene expression. Option A is incorrect because steroid receptors are proteins, not lipids or glycolipids. Option C is incorrect because typically, unbound steroid receptors are not degraded by lysosomes. Option D is incorrect because steroid receptors are found in the cytoplasm or inside the nucleus, not on the external surface of the nuclear membrane.
