The same hormone stimulates gene expression in one cell, but it inhibits gene expression in another cell. What is the BEST explanation for this difference?

Question

Quizplus · Accepted Answer

The different response to the hormone in the two cells suggests that they have different types of receptors for the hormone. Receptor proteins on the surface of cells can recognize specific signals, such as hormones or neurotransmitters, and transmit the signal into the cell via intracellular signaling pathways. The binding of a signal molecule to a receptor can result in activation or inhibition of gene expression, depending on the downstream signaling events. Therefore, the presence of different receptors can lead to different responses to the same hormone.
