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.

After frida stops exercising, she continues to breathe heavily. what is most likely occurring in her body? heavy breathing during exercise has produced an oxygen surplus in her muscles. this oxygen is being transported to her lungs. this is a result of aerobic respiration. heavy breathing during exercise has produced a carbon dioxide surplus in her muscles. lactate is being transported to her liver. this is a result of aerobic respiration. strenuous exercise has caused her body to be in carbon dioxide debt, and she is breathing hard while lactate is transported to the liver. this is a result of anaerobic respiration. strenuous exercise has caused her body to be in oxygen debt, and she is breathing hard while lactate is transported to the liver. this is a result of anaerobic respiration.
