Chapter 13, Problem 13.62EP

(a)

Interpretation Introduction

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

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

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.

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

(b)

Interpretation Introduction

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

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

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

(c)

Interpretation Introduction

Interpretation: To indicate whether the statement “an ATP molecule is used to activate a $\text{glucose 1}-\text{phosphate}$ molecule” relating to glycogenolysis 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.

Glycogenolysis is the metabolic pathway that converts glycogen to $\text{glucose 6}-\text{phosphate}$. An overview of glycogenolysis metabolic pathway is as follows:

Adenosine triphosphate (ATP) is the energy currency of life that provides energy to carry out the metabolic processes in the living cells.

(d)a

Interpretation Introduction

Interpretation: To indicate whether the statement “the equivalent of two ATP molecules are consumed” relating to glycogenolysis is true or false.
