Epinephrine can cause many different responses; it can alter glycogen metabolism, induce fat breakdown, regulate heart rate, or even have no effect on a cell's behavior. Which of the following does NOT contribute to the specificity of how a cell responds (or doesn't respond) to epinephrine signaling? Different cell types can express different epinephrine receptors that initiate different responses. None of these are true. Epinephrine diffuses only a short distance after being secreted, so only nearby cells receive the signal. Some cells lack epinephrine receptors and therefore can't respond to it. Different cell types have different effector proteins regulated by epinephrine signaling.
