biology - glycolysis +atp (help)

posted by Farah

9. The total amount of energy released from the chemical bonds of glucose is 2870 kJ/mol, after the initial investment of 2 ATP. The total energy that can be harvested to form ATP molecules is about 1200 kJ/mol.
a. After the initial investment of 2 ATP, 38 ATP are produced. How much energy was used to phosphorylate one ADP?
b. What percentage of the total energy contained in glucose is captured during glycolysis?
