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.

Identify 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.
