Activities Quiz


1 .       Which of these is responsible for initiating a signal transduction pathway? (Activity: Signal Transduction Pathway)

question #1 

 A
 B
 C
 D
 E
2 .       What role does a transcription factor play in a signal transduction pathway? (Activity: Signal Transduction Pathway) 

 By binding to a plasma membrane receptor it initiates a cascade.
 It relays a signal from the cytoplasm to the plasma membrane.
 It activates relay proteins.
 By binding to DNA it triggers the transcription of a specific gene.
 It is a plasma membrane protein that binds signal molecules.
