Steroid Hormones Bind to Receptors Inside the Cell and Alter

Multiple Choice

Steroid hormones bind to receptors inside the cell and alter their conformation. The hormone-receptor complex is then transported into the nucleus, where it can directly affect gene expression. To get from the location where the receptor binds the hormone to its site of action, the hormone-receptor complex must ________.

A) undergo another conformational change
B) become water soluble by binding to a carrier molecule
C) be transported through the nuclear pore complex
D) enter the smooth endoplasmic reticulum
