Interpretation Introduction

Interpretation: To determine the organ that produces glucagon.

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 $\text{glucose 6}-\text{phosphate}$. In the gluconeogenesis pathway, glucose is produced from non-carbohydrate substances. Hence, glucose is produced in both processes.
