Question

In general, increased sympathetic stimulation leads to
A)increases in cellular metabolism.
B)decreases in cellular metabolism.
C)no effect on cellular metabolism.
D)decreases in body temperature.
E)vasodilation of blood vessels in the skin.

Accepted Answer

Increased sympathetic stimulation activates the "fight or flight" response, which causes the release of epinephrine and norepinephrine. These hormones increase heart rate, respiratory rate, and stimulate the breakdown of glycogen to increase blood glucose levels. These processes require increased cellular metabolism, which results in increased energy production.
