Concept explainers
(a)
Interpretation: To identify the compound among ATP and creatine phosphate 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: To identify the compound among

- The first step of the metabolic process known as glycolysis is the conversion of glucose to glucose- 6-phosphate. This process has a positive value for rG' Glucose + Pi Glucose-6-phosphate + H2O rG' = +13.8 kJ/mol-rxn This reaction is coupled to the hydrolysis of ATP ATP + H2O ADP + Pi rG' = -30.5 kJ/mol-rxn What is the sum of these two equations and the value of rG' for the coupled reaction? Is the coupled reaction product-favored at equilibrium?arrow_forwardUsing symbolic formulas such as ADP and PPi, write equations for the hydrolysis of ATP to ADP and the hydrolysis of ATP to AMP.arrow_forwardCan a chemical that, in essence, goes through the body unchanged be an essential nutrient?
