Chapter 12, Problem 12.55EP

(a)

Interpretation Introduction

Interpretation: To identify the compound among ATP and phosphoenolpyruvate that releases more energy upon hydrolysis.

Concept introduction: High-energy compounds are those compounds that release a large amount of energy upon hydrolysis. These compounds consist of highly strained bonds which are responsible for the release of a high amount of energy. The compounds containing a phosphate group are examples of high energy compound.

Free energy on hydrolysis is considered as a parameter for determining the strain in the bonds. Greater the strain in the bond more will be the negative value of free energy on hydrolysis and vice-versa.

(b)

Interpretation Introduction

Interpretation: To identify the compound among creatine phosphate and ADP that releases more energy upon hydrolysis.

Concept introduction: High-energy compounds are those compounds that release a large amount of energy upon hydrolysis. These compounds consist of highly strained bonds which are responsible for the release of a high amount of energy. The compounds containing a phosphate group are examples of high energy compound.

Free energy on hydrolysis is considered as a parameter for determining the strain in the bonds. Greater the strain in the bond more will be the negative value of free energy on hydrolysis and vice-versa.

(c)

Interpretation Introduction

Interpretation: To identify the compound among $\text{glucose 1-phosphate}$ and $1,3\text{-bisphosphoglycerate}$ that releases more energy upon hydrolysis.

Concept introduction: High-energy compounds are those compounds that release a large amount of energy upon hydrolysis.

Free energy on hydrolysis is considered as a parameter for determining the strain in the bonds. Greater the strain in the bond more will be the negative value of free energy on hydrolysis and vice-versa.

(d)

Interpretation Introduction

Interpretation: To identify the compound among AMP and $\text{ glycerol }3\text{-phosphate}$ that releases more energy upon hydrolysis.
