Epinephrine Signaling Pathway

APBIO-YTH2EN

The sympathetic nervous system is responsible for the fight-or-flight response in humans. One neurotransmitter involved in this response is epinephrine. This excitatory molecule increases blood glucose by signaling the conversion of pyruvate into glucose.

Which of the following identifies a potential target receptor cell of epinephrine in the fight-or-flight response?

A

Liver cells.

B

Cells in the pancreas that produce insulin.

C

There is no specific target cell since epinephrine will work on all cells in the body and only cause a response in cells with intracellular receptors.

D

Lung cells.
