Steroid hormones work as
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 catalyze formation of cAMP
d)	None of the above

(a)

Steroid hormones are lipid soluble. So they can pass freely across the lipid bilayer of plasma membrane. After getting entrance into cytoplasm, molecules of steroids 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.
