Chapter 24, Problem 24.59EP

(a)

Interpretation Introduction

Interpretation: To indicate whether $\text{glucose }6-\text{phosphate}$ is involved in (1) glycogenesis but not in glycogenolysis, (2) glycogenolysis but not glycogenesis, (3) both glycogenesis and glycogenolysis or (4) neither glycogenesis nor glycogenolysis.

Concept introduction: 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.

Glycogenesis is the metabolic pathway that converts $\text{glucose 6}-\text{phosphate}$ to glycogen. Glycogenolysis is the metabolic pathway that converts glycogen to $\text{glucose 6}-\text{phosphate}$.

(b)

Interpretation Introduction

Interpretation: To indicate whether UDP is involved in (1) glycogenesis but not in glycogenolysis, (2) glycogenolysis but not glycogenesis, (3) both glycogenesis and glycogenolysis or (4) neither glycogenesis nor glycogenolysis.

Concept introduction: 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.

Glycogenesis is the metabolic pathway that converts $\text{glucose 6}-\text{phosphate}$ to glycogen. Glycogenolysis is the metabolic pathway that converts glycogen to $\text{glucose 6}-\text{phosphate}$.

(c)

Interpretation Introduction

Interpretation: To indicate whether glycogen is involved in (1) glycogenesis but not in glycogenolysis, (2) glycogenolysis but not glycogenesis, (3) both glycogenesis and glycogenolysis or (4) neither glycogenesis nor glycogenolysis.
