Chapter 24, Problem 24.113EP

Interpretation Introduction

Interpretation: To explain the statement “the hormone epinephrine generates a second messenger.”

Concept introduction: Hormones are the special chemical messengers that are produced by glands in the living organisms. Hormones are responsible for the regulation of psychological activities and behavioral activities, such as metabolism, sleep, growth, and development.

Glucose is a monosaccharide with the molecular formula ${\text{C}}_6{\text{H}}_{12}{\text{O}}_6$. Glycogen is a polysaccharide of glucose. It serves as a form of carbohydrate storage in humans and animals. Glycogen is a source of glucose in humans and animals. Glycogenolysis is the metabolic pathway that converts glycogen to $\text{glucose 6}-\text{phosphate}$.

Epinephrine is a hormone that is released by adrenal glands. It promotes the release of glucose from glycogen and stimulates glycogenolysis, primarily in the muscle cells.
