AP Bio Signal Transduction

What is the advantage to amplification of a signal inside of a cell?

• moderates the signal so it is not to quick

• stops a signal from being transducted

• increases the cell response to a signal

• increases the reception of signal

All mammals have a similar signaling pathway for the uptake of glucose by cells from the blood. What does this suggest about the evolutionary relatedness

• Species that use the same signal pathway are probably closely related by evolution.

• Species that use the same signal pathway are probably not closely related by evolution

• Species that use the same signal pathway will look the same anatomically

• Species that use the same signal pathway would not be in the same kingdom.
