Chapter 24, Problem 24.12EP

(a)

Interpretation Introduction

Interpretation: To identify the number of phosphate groups in $\text{2}-\text{Phosphoglycerate}$.

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 transfer of a phosphoryl group $\left({\text{PO}}_3^{2-}\right)$ is catalyzed by the kinase enzymes. In the glycolysis process, the phosphate group comes from ATP or some higher energetic phosphate molecules. The term “biphosphate” indicates that two phosphate groups are present on different carbon atoms.

(b)

Interpretation Introduction

Interpretation: To identify the number of the phosphate groups in $\text{1,3}-\text{biphosphoglycerate}$.

(c)

Interpretation Introduction

Interpretation: To identify the number of the phosphate groups in $\text{glucose 6}-\text{phosphate}$.

(d)

Interpretation Introduction

Interpretation: To identify the number of the phosphate groups in $\text{fructose 1,6}-\text{biphosphate}$.
