Steroid Hormones Bind to Receptors Inside the Cell and Alter

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 receptor-hormone 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.
