In an epinephrine-triggered signal transduction pathway, how would cellular response most likely be affected if epinephrine could not bind with the receptor
protein?
G proteins would remain inactive and prevent signal amplification from
occurring.
Nonspecific signaling would occur, and epinephrine would bind to different
receptors.
Signal amplification would occur in the extracellular fluid rather than inside the
cell.
The cell could not receive termination signals and carry out inactivation.
