Question

Signal transduction pathways benefit cells for all of the following reasons 5) EXCEPT A) Different pathways can "crosstalk" to allow one hormone to impact many cellular functions. B) Pathways offer multiple levels of coordination and fine-tuning C) They can amplify a signal. D) They enable different cells to respond appropriately to the same signal. E) Signaling pathways alleviate the need for second messengers 6) The term "estrogen response element" refers to A) a stretch of DNA that the estrogen receptor can bind to. B) an enzyme that must be phosphorylated by the estrogen receptor to become active. C) an estrogen receptor on the plasma membrane. D) a conformational change in a G-protein caused by the estrogen receptor.

Explanation / Answer

A5) They can amplify the signal.

A6) A stretch of DNA that the estrogen receptor can bind to. Estrogen receptor is a transcription factor that binds to regulatory region of  estrogen-responsive genes.
