Chapter 13, Problem 13.31EP

(a)

Interpretation Introduction

Interpretation: To indicate whether hexokinase is associated with carbohydrate digestion or the glycolysis metabolic pathway.

Concept introduction: Carbohydrates are the biomolecules composed of carbon, oxygen and hydrogen atoms. Carbohydrate molecules are joined together by glycosidic linkage.

Carbohydrates are classified as monosaccharide, disaccharide, oligosaccharide, and polysaccharide. Monosaccharides are the simplest carbohydrate units that cannot be hydrolyzed further to give the smallest units. Disaccharides contain two monosaccharide units. Oligosaccharides contain 3 to 10 monosaccharide units. Polysaccharides contain many carbohydrate units that vary from 100 to 50,000 monosaccharide units.

In the glycolysis metabolic pathway, a glucose molecule breaks down and is converted into two pyruvate molecules along with the production of two ATP molecules and NADH coenzymes.

The block diagram to represent an overview of glycolysis is as follows:

From the above diagram, it is concluded that in the overall process of glycolysis, two stages are present.

a) Steps 1 to 3 represents a six-carbon stage $\left({\text{C}}_6\text{ stage}\right)$.

b) Steps 4 to 10 represent a three-carbon stage $\left({\text{C}}_3\text{ stage}\right)$.
