Hormones???

Question

How does an amino acid based hormone get its signal from outside the cell to the inside where it causes a response?

Answer 1

Amino acid steroids travel through the blood stream to the target cell. There, they attach to extracellular receptors that initiate cellular response. Once these receptors become activated, they activate additional receptors, or secondary messengers, within the cell. These messengers in turn activate more receptors and so on down the line. This is called the cascading effect, it amplifies the response of the cell to a steriod. Eventually, certain factors that can initiate transcription are activated. This leads to translation and proteins, which effect cellular response.
