Which of the Following is True of Steroid Receptors

Question

Which of the following is true of steroid receptors?
A)The receptor molecules are themselves lipids or glycolipids.
B)The receptor may be inside the cell or nucleus of a target cell.
C)The unbound steroid receptors are quickly recycled by lysosomes.
D)Steroid receptors are plasma membrane bound.
E)Steroid receptors are active until steroid binds.

Accepted Answer

Steroid receptors may be located inside the cell or nucleus of a target cell. They are typically cytoplasmic or nuclear proteins that bind to steroid hormones and activate gene transcription. The other options are incorrect as steroid receptors are not themselves lipids or glycolipids, are not plasma membrane bound, and are not quickly recycled by lysosomes. Steroid receptors also require the binding of steroid to become active.
