Chapter 24, Problem 24.69EP

(a)

Interpretation Introduction

Interpretation: To indicate whether $\text{glucose 6}-\text{phosphate}$ is associated with (1) glycolysis, (2) glycogenesis, or (3) 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.

(b)

Interpretation Introduction

Interpretation: To indicate whether UTP is associated with (1) glycolysis, (2) glycogenesis, or (3) glycogenolysis.

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

Glycolysis is the metabolic pathway that breaks down a glucose molecule and converts it into two pyruvate molecules along with the production of two ATP molecules and NADH reduced coenzymes.

Uridine triphosphate (UTP) is a triphosphate nucleotide that provides energy to carry out the metabolic processes in the living cells.

(c)

Interpretation Introduction

Interpretation: To indicate whether phosphoglucomutase is associated with (1) glycolysis, (2) glycogenesis, or (3) glycogenolysis.

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

Glycolysis is the metabolic pathway that breaks down a glucose molecule and converts it into two pyruvate molecules along with the production of two ATP molecules and NADH reduced coenzymes.

(d)

Interpretation Introduction

Interpretation: To indicate whether pyruvate is associated with (1) glycolysis, (2) glycogenesis, or glycogenolysis.

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

Pyruvate $\left({\text{CH}}_3{\text{COCOO}}^{-}\right)$ is the conjugate base of pyruvic acid $\left({\text{CH}}_3\text{COCOOH}\right)$.
