The Delta G° for the complete in vitro combustion of glucose to CO2 and H2O id -2973 kJ/mol. The Delta G for hydrolysis of one ATP molecule in the cell (at a realistic intracellular concentration of 5mM) is considered to be -50 kJ/mol. Use these two values to answer the following questions.
a) How many ATP are produced in cells during complete oxidation of one glucose molecule under aerobic conditions, including oxidative phosphorylation? Justify your answer.
b) What is the total energy (in kiloJoules) of these ATP molecules formed under aerobic conditions? [Hint: use your answer from part a) and make the calculation!] What fraction of the total energy in the original glucose molecule is transferred to ATP? Show your work.
c) How many ATP are produced from that glucose molecule under anaerobic conditions? What is the total energy (in kiloJoules) in these ATP molecules? What fraction of the total energy in glucose is transferred to ATP? Compare the amount of energy converted to the values you calculated in parts a) and b) above. Show all work and justify your answers.
d) What happens to the rest of the energy in that glucose original molecule?
