Chapter 24, Problem 24.61EP

(a)

Interpretation Introduction

Interpretation: To indicate whether the statement “$\text{glucose 1}-\text{phosphate}$ is an intermediate in the process” relating to glycogenesis is true or false.

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.

In the isomerization reaction, a molecule transformed itself to another molecule, having the same number of atoms with a different arrangement.

An intermediate is defined as the transient species that is formed from the reactants in the preceding step and gets consumed in the subsequent steps to generate the products. An intermediate is formed within a multi-step reaction mechanism.

(b)

Interpretation Introduction

Interpretation: To indicate whether the statement “an isomerization reaction changes $\text{glucose 1}-\text{phosphate}$ to $\text{glucose 6}-\text{phosphate}$” relating to glycogenesis is true or false.

(c)

Interpretation Introduction

Interpretation: To indicate whether the statement “a UTP molecule is used to activate a $\text{glucose 6}-\text{phosphate}$ molecule” relating to glycogenesis is true or false.

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.
