A) they enter into target cells and binds with specific receptor and activates specific genes to form protein
B) they binds to cell membrane
C) they catalyse formation of c-AMP
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 entrance 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 gene that ultimately produce specific proteins.
