A) they enter into target cells and bind with specific receptor and activate specific genes to form protein
B) they bind to cell membrane
C) they catalyse formation of cAMP
D) None of the above
Correct Answer: A
Solution :
Steroid hormones are lipid soluble. So, they can pass freely across the lipid bilayer of plasma membrane. After getting into the cytoplasm, molecules of steroid hormones bind to receptor molecules, located within the cytoplasm of target cell and thus a hormone receptor complex is formed. Now, this complex moves into the nucleus of the cell and activates specific genes that ultimately produce specific proteins.
