Final answer:
Glucagon and epinephrine both raise blood glucose levels by stimulating different processes such as glycogenolysis and gluconeogenesis. This helps maintain homeostasis.
Step-by-step explanation:
Glucagon and epinephrine both have direct effects on blood glucose levels. Glucagon raises blood glucose levels by stimulating glycogenolysis and gluconeogenesis, which break down stored glycogen and synthesize glucose from amino acids and glycerol. Epinephrine, on the other hand, increases the availability of glucose to muscles by stimulating glycogenolysis in liver cells. These actions result in an increase in blood glucose levels to maintain homeostasis.
