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.
