Concept explainers
(a)
Interpretation: To determine the number of phosphorus-oxygen bonds that is broken in the conversion of ADP to AMP via a hydrolysis reaction.
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. ADP and AMP are examples of high energy compounds.
ADP and AMP contain the adenine base, the ribose sugar unit and phosphate groups in their structure. They only differ in the number of phosphate group present in them. Adenosine diphosphate (ADP) consists of two phosphoryl groups

- 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?
