The total amount of energy contained in the chemical bonds of glucose is 2870 kJ/mol (180.16 g). The total amount of energy collected as an ATP molecule during glycolysis is 122 kJ/mol of glucose. a) How much energy does an ATP molecule capture during its formation? b) What percentage of the total energy contained in glucose is captured during glycolysis?

Calculate the overall efficiency of oxidative phosphorylation, assuming standard conditions, by comparing the free energy potentially available from the oxidation of NADH by O2 and the free energy required to synthesize 2.5 ATP from 2.5 ADP.

During glycolysis, glucose is converted to glucose 6-phosphate: (1) Glucose → glucose 6-phosphate; ∆G'° = +14.1 kJ/mol. (2) ATP + H2O ↔ ADP + Pi; ∆G'° = -31 kJ/mol The ∆G'° of glucose phosphorylation is: A) +8.8 kJ/mol B) +17 kJ/mol C) -45 kJ/mol D) -5.4 kJ/mol E) -16.9 kJ/mol
