The receptors for steroid hormones are located inside the cell instead of on the membrane surface like most other signal receptors. This is NOT a problem for steroids because ________.
A) the receptors can be readily stimulated to exit and relocate on the membrane surface
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

Question

Quizplus · Accepted Answer

Steroid hormones are lipid soluble, allowing them to diffuse through the lipid bilayer of the cell membrane and bind to the receptors located inside the cell. This is not a problem for steroids because they can easily cross the membrane to reach their target receptors.
