How do protein hormones and steroid hormones differ in how they affect target cells?
What will be an ideal response?
Protein hormones bind to receptors on the cell membrane of their target cells. This binding initiates a series of chemical reactions that ends with the cell's response to the hormone. Steroid hormones cross the cell membrane and bind to receptors in either the cytoplasm or nucleus of target cells. The hormone and receptor then bind to DNA in the nucleus and directly affect gene transcription.
