The tоp figure shоws fоur signаling pаthwаys, labeled 1 through 4. All pathways begin with the same receptor being triggered by the same signaling molecule. However, the secondary messengers that follow are ordered differently among the pathways. The bottom figure shows a relationship between the presence or absence of an activated protein X and the activity of protein W. Which signaling pathways are consistent with the data presented in the bottom figure? Select all that apply.
