Concept explainers
(a)
Interpretation: To determine the structural difference between ADP and AMP.
Concept introduction:
(b)
Interpretation: To determine the structural difference between ATP and CTP.
Concept introduction: Nucleotide is the basic unit required for the formation of nucleic acid which is required for completion of various metabolic reactions. The basic structure of nucleotide consists of three units: nitrogen-containing base, a pentose sugar, and a phosphate group. The nitrogen-containing base and pentose sugar are collectively known as a nucleoside. A nucleoside unit attached to a phosphate group together forms a nucleotide unit. ATP, AMP, ADP, and CTP are examples of nucleotides present in the human body.

- 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_forwardWhy are so many different enzymes needed?arrow_forwardThe terminal electron acceptor of the Electron Transport Chain? A. B. C. Cytochrome C D. Coenzyme Q E. ATP Fe (III) 0₂arrow_forward
