Chapter 24, Problem 24.9EP

(a)

Interpretation Introduction

Interpretation: To indicate whether the intermediate $fructose 6−phosphate$ in the glycolysis pathway is a $C6$ molecule or a $C3$ molecule.

Concept introduction: 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 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 $(C6 stage)$ .

b) Steps 4 to 10 represent a three-carbon stage $(C3 stage)$ .

In the $C6$ stage, the intermediates are derivatives of either glucose or fructose. Glucose and fructose contain six carbon atoms. Therefore, they are $C6$ molecules. The phosphate groups are present in the intermediates.

In the $C3$ stage, the intermediates are phosphorylated derivatives of glyceraldehyde, pyruvate, glycerate, or dihydroxyacetone, which are derivatives of either acetone or glycerol. Acetone and glycerol contain three carbon atoms. Therefore, they are $C3$ molecules.
