Question

Quizplus · Accepted Answer

Steroid hormones are lipid-soluble molecules that can easily pass through the plasma membrane of a cell. Once inside the cell, a steroid hormone would bind to a specific receptor protein located in the cytoplasm or nucleus. The hormone-receptor complex then acts as a transcription factor, either enhancing or suppressing the transcription of specific genes in the cell's DNA. Therefore, a cell that is affected by a particular steroid hormone would be expected to have a receptor inside the cell that binds the hormone.
