Final answer:
Epinephrine, glucagon, and cortisol are hormones that help to maintain and increase blood glucose levels during exercise. Glucagon increases blood glucose levels by stimulating the breakdown of glycogen to glucose in muscle cells and liver cells. It also stimulates the liver to convert amino acids into glucose through a process called gluconeogenesis.
Step-by-step explanation:
Epinephrine, glucagon, and cortisol are hormones that help to maintain and increase blood glucose levels during exercise. When blood glucose levels decline below normal levels, glucagon is released by the pancreas. Glucagon increases blood glucose levels by stimulating the breakdown of glycogen to glucose in muscle cells and liver cells. It also stimulates the liver to convert amino acids into glucose through a process called gluconeogenesis. Glucagon plays a critical role in maintaining blood glucose levels during exercise and periods of fasting.
