Steroid hormones do not interact with plasma membrane receptors on target cells because they ____.
A)are small enough to pass directly through pores in the plasma membrane
B)are lipid soluble and pass through the lipid bilayer
C)pass through special channels in the plasma membrane
D)are water soluble
E)dissolve in the cholesterol of the plasma membranes

Question

Quizplus · Accepted Answer

Steroid hormones are lipid soluble, allowing them to pass through the lipid bilayer of the plasma membrane and enter the cytoplasm of the target cell where they interact with intracellular receptors. They do not interact with plasma membrane receptors because they cannot dissolve in the aqueous environment surrounding the plasma membrane.
