The Receptors for Steroid Hormones Are Located Inside the Cell

question 10

Multiple Choice

• B) steroids do not directly affect cells but instead alter the chemistry of blood plasma
• C) steroid hormones are lipid soluble, so they can readily diffuse through the lipid bilayer of the cell membrane
• D) steroids must first bond to a steroid activator, forming a complex that then binds to the cell surface
