A target cell that is affected by a particular steroid hormone would be expected to have
A) an intracellular receptor protein that binds the hormone.
B) a cell-surface receptor protein that binds the hormone.
C) enzymes that are activated or inactivated by the intracellular hormone-receptor complex.
D) enzymes that are activated or inactivated by the hormone's second messenger.

Question

Quizplus · Accepted Answer

Steroid hormones are lipophilic and can easily diffuse through the cell membrane. They bind to intracellular receptors, forming hormone-receptor complexes that bind to specific DNA sequences and affect gene expression. Therefore, the target cell affected by a steroid hormone should have an intracellular receptor protein that binds the hormone.
