Glucagon works by:

a. binding to hormone response elements on dna and stimulating glycogenolysis and gluconeogenesis.
b. binding to hormone response elements on dna and stimulating glycogenesis.
c. activating second messengers and stimulating glycogenolysis and gluconeogenesis.
d. activating second messengers and stimulating glycogenesis.

option C - activating second messengers and stimulating glycogenolysis and gluconeogenesis.

Explanation:

Glucagon is an hormone, produced by the pancreas, that opposes the action of insulin by stimulating the production of SUGAR.

Glucagon is usually released whenever blood glucose levels is detected to be LOW. it works by activating secondary messengers.

imagine a line passing through the center of earth that goes through both the north pole and the south pole. this imaginary line is called an axis. earth spins around its axis, just as a top spins around its spindle. this spinning movement is called earth's rotation. at the same time that the earth spins on its axis, it also orbits, or revolves around the sun. this movement is called revolution.
